Step-by-step explanation:

this is the answer guys.

Answer:

x+1 , x<-1

x²-bx-4  , -1≤x≤4

1/2 x +a

substitute x=-1 , continuous everywhere

x+1=x²-bx-4 when x=-1

-1+1=-1²-b-4

then for :

x²-bx-4=1/2 x +a for x=4

4²-4b-4=1/2x+a

16-4(3)-4=4/2+a

16-12-4-2=a

the equations will be :

x+1

x²-3x-4

1/2x-2

Answer:

f(4) = -10

x = 0

Step-by-step explanation:

From the graph attached,

For x = 4,

Value of the function will be,

f(4) = y value at x = 4

f(4) = -10

Similarly, for y = g(x) = 2,

x value of the function will be,

x = 0

For which g(0) = 2

Therefore, for x = 0 value of the function will be 2.

g(0) = 2

Answer:

f(4) = -10

Answer & Step-by-step explanation:

This is what is called an arithmetic sequence. An arithmetic sequence adds the same number every time. If we take and subtract the 3rd term from the 4th term, we get 21. However, when we subtract 17 from 26 or 26 from 44, we get 9 and 18 respectively, which is not in keeping with the sequence.

Answer:

255 F

Step-by-step explanation:

133 + 122 = 225.

So that is the answer.

133°F is 255 degrees warmer than -122°F.

To find out how many degrees warmer 133°F is than -122°F, we can subtract the two temperatures:

Temperature difference = 133°F - (-122°F)

Remember that subtracting a negative number is the same as adding its positive value, so the calculation becomes:

Temperature difference = 133°F + 122°F

Temperature difference = 255°F

So, 133°F is 255 degrees warmer than -122°F.

Answer:

Step-by-step explanation:

5 (2x - 8) = 90

5 × 2x - 8 = 90

2x - 8 = 90 ÷ 5

2x - 8 = 18

2x = 18 + 8

2x = 26

2x/2 = 26/2

x = 13

13 is the answer to the question.

Answer: A and D

Step-by-step explanation:

The function is positive when the graph is above the x-axis.

in the image we can see that the graph is above in between the points:

x = - 5 and x = 0, then goes bellow, and then comes up again at x = 3.5 and the graph ends at x = 4.

Then the regions where the function is positive are:

-5 < x < 0 and 3.5 < x < 4

Then the correct options are:

A and D

Answer:

B

Step-by-step explanation:

Option b is our correct answer.

2, 6 , 10b, and -8a.

Given,

2 + 6 + 10b - 8a

We need to find the terms in the expression.

Every expression is made of terms.

Example:

ax² + bx + c + d

ax², bx, c and d are the four terms that make the expression.

Example:

ax² - bx - c - d

ax², - bx, - c  and - d are the terms in the expression.

Remember to take the sign along with the terms.

Find the terms in the expression.

We have,

2 + 6 + 10b - 8a

2  - one expression

6 - one expression

10b - one expression

-8a - one expression

Thus,

Option b is our correct answer.

2, 6 , 10b, and -8a.

Answer:

Step-by-step explanation:

got it right on edge

The domain restriction is x ≥ 1 and inverse function is f⁻¹(x) = 1+√(x+1)

An inverse function is a function that returns the original value for which a function has given the output. If f(x) is a function which gives output y, then the inverse function of y, i.e. f-1(y) will return the value x.

Given:

f(x) = x² – 2x

We can find the inverse function by solving for y:

x = f(y)

x = y² -2y

x +1 = y² -2y +1

x +1 = (y -1)²

√(x +1) = y -1

1 +√(x +1) = y

So, the inverse function is

[tex]f^{-1}[/tex](x) =   1 +√(x +1)

Thus, the minimum value of x for which the original function has this as an inverse is 1.

So, The domain restriction is x ≥ 1 and inverse function is f⁻¹(x) = 1+√(x+1)
