Find the zero (s) of the following functions algebraically: f (x) = 3x-21

x=7

Step-by-step explanation:

The function is:

f (x) = 3x-21.

The zero (s) is/are any value (s) that make (s) the function equal (s) to zero.

This implies that, to find the zero (s), we equate the function to 0 and solve for x

This implies that:

3x-21=0

3x=21

Dividing through by 3, we obtain

x=7
