Question

What are the zeros of the function f(x)=16x-0.04x^2

Answer 1

400 or 0

Explanation:

The zeros of a function are values of x that will cause f(x) to become zero

i.e

16x-0.04x² = 0 (factorizing x)

x (16-0.04x) = 0

thus either

x = 0 (one of the zeros)

or (16-0.04x) = 0

0.04x = 16

x = 16 /0.04

x = 400 (other zero)

hence the zeros are x = 400 or 0
