Question Identify the initial amount a and the rate of decay r (as a percent) of the exponential function y=8(1−0.15)t. Evaluate the function when t=3. Round your answer to the nearest tenth.
When t=3,

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

step-by-step explanation:

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.
