Is f(x)=4x2−3 a one-to-one function on the domain (−∞,∞)?
Options:
-No, f(x)=4x2−3 is not a one-to-one function on (−∞,∞) because there is an output value that has more than one corresponding input value.
-Yes, f(x)=4x2−3 is a one-to-one function on (−∞,∞) because there is an output value that has more than one corresponding input value.
-Yes, f(x)=4x2−3 is a one-to-one function on (−∞,∞) because each output value has exactly one input value.
