Question

Find the zero of the function f(x)= 4x+8

Answer 1

The zero of the function is at x = -2

Explanation:

Answer 2

x = -2

Explanation:

Solve for x:

4 x + 8 = 0

Subtract 8 from both sides:

4 x + (8 - 8) = -8

8 - 8 = 0:

4 x = -8

Divide both sides of 4 x = -8 by 4:

(4 x)/4 = (-8)/4

4/4 = 1:

x = (-8)/4

8/4 = (4×2)/4 = 2:

Answer: x = -2
