Question

The coordinate plane shows the graph of the function f(x)=x^4−2x^2+1. The function is defined for all real numbers. Which statement is not true for the function shown in the graph?

A. The function has symmetry with respect to the y-axis.
B. The function has a domain that is all real numbers.
C. The function has a range that is all real numbers.
D. The function has two zeros located at –1 and 1.

Answer 1

C. The function has a range that is all real numbers.

Explanation:

Y has restraints- it doesn't go below 0

therefore it isn't all real numbers. it's more like y≥0
