Question

F(x) = -5x² reflection in the x-axis:

a) f(x) = 5x²
b) f(x) = -5x²
c) f(x) = -5x⁻²
d) f(x) = 5x⁻²

Answer 1

The reflection in the x-axis of a function f(x) can be obtained by changing the sign of the function.

Step-by-step explanation:

The reflection in the x-axis of a function f(x) can be obtained by changing the sign of the function. So, if f(x) = -5x², the reflection in the x-axis would be f(x) = 5x². Therefore, the correct option is a) f(x) = 5x².
