Revolt · Accepted Answer

✔ negative infinity to infinity; The domain of this function is .: negative infinity to infinity

Question 6

b =

Revolt · Accepted Answer

1/2

Question 7

How does the graph of y = 3x compare to the graph of y = 3–x?

Revolt · Accepted Answer

The graphs are reflected across the y-axis.

Question 8

Which function is graphed on the right?y = 2x+3 – 2y = 2x–3 + 2y = 2x–2 + 3y = 2x–2 – 3

Revolt · Accepted Answer

y = 2x–2 – 3

Question 9

How can you use transformations to graph this function? Explain your steps.

Revolt · Accepted Answer

Start with y = 7^x. Reflect it across the y-axis to get y = 7^{-x}, stretch it vertically by a factor of 3 to get y = 3(7^{-x}), and shift it up 2 units to get y = 3(7^{-x}) + 2. The horizontal asymptote is y = 2.

Question 10

How does the graph of y = 3–x compare to the graph of

Revolt · Accepted Answer

The graphs are the same.
