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.

A.x = 4
B.x = −7 and x = 4
C.x = −7 and x = 2

B. x = −7 and x = 4
C.x = −7 and x = 2
since (2,1) is on the curve
Yes, that is correct. I apologize for the oversight. The correct answer is C. x = −7 and x = 2, since the points (−7, 1) and (2, 1) lie on the curve. Thank you for pointing that out.
