Question

Which input value produces the same output value for the two functions on the graph?

x = –3
x = –1
x = 1
x = 3

Answer 1

X=3

Explanation:

We have two linear functions which intersect at a point. Linear functions are lines which are made of points that satisfy the function or relationship. This means at the intersection, this point (3,-1), both functions have values. An input of x=3 produces y=-1 in both functions.
