Question

3. Use your graphing calculator to find the value of f'(0) for f(x) = cos(x) - eX. (4 points)

Answer 1

-1

Explanation:

Derivative of cos(x)=-sin(x)

Derivative of e^x=e^x

Derivative of cos(x)-e^x= - sin(x)-e^x

plug in 0 to the spots of x and you will get 1 because sin(0) is 0 e^0 is 1

0-1=-1
