Question

anisha is graphing the function f(x) = 25(3/5)x. She begins by plotting the point (1, 15). Which could be the next point she plots on the graph? (2, 9) (2, –10) (2, 14) (2, 5)

Answer 1

Answer:

(2, 9)

Step-by-step explanation:

We've been given the exponential function;

f(x) = 25(3/5)^x

We need to determine the value of f(x) when x = 2, that is;

f(2) = 25(3/5)^2

Using a calculator we obtain

f(2) = 9

Thus the next point she plots on the graph will be (2, 9)
