Question

On a coordinate plane, an exponential function approaches y = 0 in quadrant 2 and increases into quadrant 1. It goes through (negative 1, 1.5), (0, 3), (1, 6).

Which exponential function is represented by the graph?

f(x) = 2(3x)
f(x) = 3(3x)
f(x) = 3(2x)
f(x) = 2(2x)

Answer 1

c

Explanation:

Answer 2

f(x)=3(2x)

Explanation:

Just plug in 1 for x & see which function produces 6. This works because when x=1 on the graph, y=6, therefore the correlating function would have to produce those numbers as well.
