Question

1.) Determine whether f is an exponential function of x. If so, find the constant ratio.

A.) f is not an exponential function.

B.) f is an exponential function with a constant ratio of 1/2.

C.) f is an exponential function with a constant ratio of 2.

D.) f is an exponential with a constant difference of 2.

2.) What change do you have to make to the graph of f (x) = 11x in order to graph the function g (x) = 11x + 12?

Shift the graph _____ units _____.

A.) 11, up

B.) 12, down

C.) None of these

D.) 12, up

E.) 11, down

Hi can you please explain and solve thank you

Answer 1

Hello, Jordon,

I can't help much with the first question. Are the numbers in the table correct? It seems to start as a parabola, but the values when x = 1 and 2 suggest a straight line. I can't envision what this equation looks like. Sorry.

The second question involvs a straight line. We're adding 12 to shift the line up by 12. So choice D looks promising. Try graphing the two equations:

fy = 11x

y = 11x + 12

You'll see the difference.
