Question

using the graph of ( y = f(x) ) to the right, and given that the zero of the function is ( x = 20 ), find the following.
(a) the ( x )-intercept of the graph of ( y = f(x) )
(b) the solution to the equation ( f(x) = 0 )
(a) the ( x )-intercept of the graph is ( x = square ).
(b) the solution to the equation ( f(x) = 0 ) is ( x = square ).

Explanation:

Step1: Relate zero to x-intercept

The zero of a function is the x-value where the graph crosses the x-axis, which is the x-intercept. We are given the zero is $x=20$.

Step2: Connect f(x)=0 to zero

The solution to $f(x)=0$ is the x-value where the function equals 0, which is the zero of the function.

Answer:

(a) $20$
(b) $20$
