Question

If f(x) = 2x + 3 and g(x) = −x + 6, use the graph to find the solution to the equation f(x) = g(x).

A) x = 1
B) x = 0
C) x = −3 or x = 0
D) x = −3 or x = 1

Answer 1

A) x = 1

Explanation:

x = 1 The lines given by y = 2x + 3 and y = −1x + 6 only intersect at (1, 5), thus x = 1 is the only real solution to the equation 2x + 3 = −1x + 6.
