Question

Which point is on the graph of f(x)= 3 • 4^x?

Answer 1

The answer is C. (1, 12).

12 = 3 x
`4^(1)`

Answer 2

Explanation:

f(x)= 3 • 4^x

we can use the x coordinate of the points given in option to check what value do we get for y or f(x) .

so using the point from first option A :

x= 12

`y=f(12)=3.4^(12)=50331648\\eq 1`

for option B

x=0

`y=f(0)=3.4^0=3`

option C

x=1

`y = f(1)= 3.4^1=12`

so the correct option is C
