Consider the function below. f(x) = -5x² + 30x + 5 Exercise (a) Find the critical numbers of f. Step 1 Differentiate f(x) = -5x²

Question

Consider the function below.
f(x) = -5x² + 30x + 5
Exercise (a)
Find the critical numbers of f.
Step 1
Differentiate f(x) = -5x² + 30x + 5 with respect to x.
f'(x) = -10x +30
Step 2
To find the critical numbers, set f'(x) = 0 and solve for x. (Enter your answers as a comma-separated list.)
-10x + 30 = 0
