Question

The graph represents the function f(x) = 10(2)x.

On a coordinate plane, an exponential growth function approaches y = 0 in the second quadrant and goes through points (negative 1, 5), (0, 10), (1, 20), (2, 40).
How would the graph change if the b value in the equation is decreased but remains greater than 1? Check all that apply.

Answer 1

Explanation:

Here you have an exponential function. The proper format is

f(x) = 10(2)^x, where the " ^ " represents exponentiation.

If (-1, 5) is a point on this graph, then 5 = 10(2)^1 must be true. Then

5 = 10(2)^(-1) => 5 = 10/2 = 5. This is true.

You mention a "b value" but do not show it in the equation. Please repost this question and show b.

Answer 2

Options C and D.

Hope it works!
