Question

what type of function is f(x)=2e^-3x?

i have the options of exponential decay, exponential growth, quadratic and linear function

Answer 1

Linear is y = mx + b. Quadratic is y = Ax² + Bx + C.

This equation is an exponential function. Because of the negative sign, the values of f(x) get smaller as x gets larger. So, it's exponential decay.
