Question

The quadratic function f(x)=-0.17x² is the reflection of __________ over the x-axis.

f(x)=0.17x²
f(x)=x²
f(x)=ax²
f(x)=-x²

The correct answer is: f(x)=0.17x²

$f left parenthesis x right parenthesis equals negative a x squared text is the reflection of end text f left parenthesis x right parenthesis equals a x squared text over the end text straight x text -axis. end text$
So the answer is
As f(x)=-0.17x² opens downwards whereas, f(x)=0.17x²opens upwards.
