Question

Consider the functions shown on the graph.

A coordinate grid with two lines. One line labeled f(x) and passes through (negative 3, 1), (0, 1), and point (1.5, 1). The second line is labeled g(x) and passes through point (0, negative 1), point (1.5, 1), and point (3, 3).

What is the best approximation for the input value when f(x)=g(x)?

0.0
0.5
1.5
3.0

Answer 1

1.5

Reason: f(x) is the constant line y = 1, and g(x) passes through (1.5, 1), so the two functions are equal at x = 1.5.
