Question

F(x) = -12x + 48
What is the zero of the following linear function?

Answer 1

x = 4

Explanation:

To find the zero, let f(x) = 0, that is

- 12x + 48 = 0 ( subtract 48 from both sides )

- 12x = - 48 ( divide both sides by - 12 )

x = 4

Answer 2

Answer: 4

Explanation:

The zero of a function is the value of the unknown at which the function is zero.

f(x) = -12x + 48

we will equate f(x) to zero , that is

0 = - 12x + 48

12x = 48

divide through by 12

x = 4

Check: let us substitute x = 4 into the function

f(x) = -12(4) + 48

f(x) = -48 + 48

f(x) = 0

Therefore, 4 is the zero of the linear function
