Question

an analyzing a function, John finds that f(3)=7. This means that the graph of f passes through the point
A. (0,7) B. (3,0) C. (3,7) D. (7,3)

Answer 1

Hi

Functions are written as f(x)
But that f(x) is the same thing as y
So we plug in an x value and get the y-value

For example: f(x) = 3x
If we plug in x = 3, we get
f(3) = 3*3
f(3) = 9

we find out that the y-value is 9
so our point is (3, 9)

Answer 2

so for your question

f(3) = 7

what is the point that would be on the line?
