Answer 1

@Vocaloid

Answer 2

Do you know how to approach this problem?

Answer 3

no

Answer 4

Alright so this is an exponential function. An exponential function has the formula \[y=a^x\] where the a is the y value of the point (1, y) in a normal function (meaning the graph is not reflected at the y-axis)

Answer 5

What do you suppose the a variable is, looking at the first graph f?

Answer 6

1

Answer 7

Remember, the a value is the y in the point (1, y)

Answer 8

3?

Answer 9

Yep! So the formula for the f graph is \[y=3^x\]

Looking at transformations, what do you think the g graph is? Remember that the g and f is similar.

Answer 10

-1/3?

Answer 11

The negative would make the graph in the third and fourth quadrants. 1/3 is correct.
