Give the equation of the exponential function whose graph is shown
40

D. f(x) = 2⁻ˣ

Plotting the equation would make the line function like this:

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
