Question 9 1 points Save Answer Suppose f(x)-10. Calculate the derivative f(x)- x-2, that is, calculate f(2)- and evaluate it at Notes: If you have for example f(x)-4xA5, then its derivative is 20xA4. Enter this answer as "20x*4" (i.e. without the multiplication sign " and using only the exponent symbol"A"itf needed, don't use the quotation marks) In the first box enter the general derivative, in the second one enter the numerical value of the derivative at the specified value for x. That is, if we are asked to calculate f(1) for the above function, you would enter simply "20" (again without the quotation marks).

Explanation / Answer

(Question 9)

f(x) = 10 (a constant). Therefore,

f'(x) = d/dx(10) = 0

f'(2) = 0

(Question 10)

f(x) = 10 + 5x2

f'(x) = d/dx(10) + d/dx(5x2) = 0 + 10x = 10x

f'(2) = 10 x 2 = 20
