Question
The quadratic function f(x) = 6.5 x2 is the reflection of __________ over the x - axis.
- f(x) = 0.17 x2
- f(x) = x2
- f(x) = a x2
- f(x) = - 6.5 x2
The correct answer is: f(x) = - 6.5 x2
is the reflection of 
over the x - axis.
The quadratic function f(x)= 6.5x2 is the reflection of f(x)= -6.5x2 over the x-axis.
As f(x)= -6.5x2 opens downwards whereas, f(x)= 6.5 opens upwards.
