Question

given the following exponential function below, what is the value of f(1/2)? round to the nearest hundredth. f(x)=-e^2x-3
a.-4.72
b.-5.72
c.-3.72
d.- 2.72

Answer 1

which one is it?

\[\Large f(x) = -e^{2x}-3\]

or

\[\Large f(x) = -e^{2x-3}\]

Answer 2

\[\Large f(x) = -e^{2x}-3\]

\[\Large f(1/2) = -e^{2(1/2)}-3\]

\[\Large f(1/2) = -e^{1}-3\]

I'll let you finish. You would type e^1 - 3 into your calculator to get the approximate value.
