Question

The figure shows the graphs for functions and .

It is stated that the functions and are determined by:
() = +4
() = 10 − 2x
how do I set up an equation that can be used to determine the first coordinate of the intersection of the graphs?

Answer 1

Explanation:

At the point of intersection the coordinate can be found with

10 - 2x = 4 (is the required equation).

Solving this we find the first coordinate (x) to be 3.
