Given fx 11x2 16 find f0 and solve fx 0 I figured out the f

Given f(x)= 11x^2 -16, find f(0) and solve f(x) = 0. I figured out the first part but im stuck on the second.

1. f(0) = -16

2. The solution to f(x) = 0 is attained when x = _ _

Solution

Solution:

Given that

f(x)= 11x^2 -16

1. to find f(0) we need to plug x = 0 in f(x)

f(0) = 11 (0)² -16

f(0) = 0-16 = -16

2.

f(x) = 0

11x^2 -16 = 0

11 x² = 16

x² = 16 / 11

x = 4 / 11 . and x = - 4/11
