Answer:
A.
Step-by-step explanation:
If you use the vertical line test only one point hits the graph.
It is 9 because all the other numbers are in the 80s and 90s 9 is way to low.
The value of f(19) in the given equation is 55.
<h3>What is the function of a linear equation?</h3>
The function of a linear equation illustrates a straight line graph and for a given set of input into the function, there is usually a specific output.
Given that:
We are to find the f(x) = 19.
So;
f(19) = 3(19) - 2
f(19) = 57 - 2
f(19) = 55
