I NEED HELP WITH FUNCTIONS

Answer 1

Which exponential function goes through the points (1, 8) and (4, 512)?

f(x) = 4(2)x

f(x) = 8(2)-x

f(x) = 4(4)-x

f(x) = 2(4)x

Answer 2

i think its A

Answer 3

for the first one?

Answer 4

yea function thing

Answer 5

The function f(x) is shown below:

f(x) = (4)x + 5

The function f(x) is shifted to the right by 13 units. Which of the following best represents the new function?

f(x) = (4)x - 8

f(x) = (4)x + 13

f(x) = (4)x + 18

f(x) = (4)x - 13

Answer 6

Sabrina is using an online calculator to calculate the outputs f(n) for different inputs n. The ordered pairs below show Sabrina's inputs and the corresponding outputs displayed by the calculator:

(1, 6), (2, 11), (3, 16), (4, 21)

Which of the following functions best represents the rule that the calculator uses to display the outputs?

f(n) = 5n - 1

f(n) = 5n + 1

f(n) = 4n + 3

f(n) = 4n - 3

Answer 7

Wendy initially has 6 hours of pop music and 3 hours of classical music in her collection. Every month onwards, the hours of pop music in her collection is 9% more than what she had the previous month. Her classical music does not change. Which function shows the total hours of music she will have in her collection after x months?

f(x) = 6(1.09)x + 3

f(x) = 3(1.09)x + 6

f(x) = 6(0.09)x + 3

f(x) = 3(0.09)x+ 6

Answer 8
