On a coordinate plane, solid circles appear at points (negative 7, 1), (negative 6, 4), (negative 2, 8.5), (negative 1, 7.75), (1, 4), (2, 1). A curved line connects these points in an arc.

Use the graph to determine the input values that correspond with f(x) = 1.

x = 4
x = 1 and x = 4
x = −7 and x = 4
x = −7 and x = 2

1 answer

The input values that correspond with f(x) = 1 are x = 4.
