F (x) = - 12x + 48

What is the zero of the following linear function?

Answer: 4

Step-by-step 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

x = 4

Step-by-step 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
