Question

Giselle graphs the function f(x) = x2. Robin graphs the function g(x) = –x2. How does Robin’s graph relate to Giselle’s?

Answer 1

Answer: A) Robin´s graph is reflection of Giselle´s graph over the x-axis.

Answer 2

Answer:

Robin’s graph is a reflection of Giselle’s graph over the x-axis

Step-by-step explanation:

Giselle graphs the function f(x) = x2. Robin graphs the function g(x) = –x2.

Giselle graphs the function f(x) = x^2.

The quadratic equation is in the form of y=ax^2 + bx+c

when a= positive then parabola opens up

when a= negative then parabola opens down

f(x)= x^2 the graph of parabola opens up

g(x)= -x^2 , the graph of the parabola opens down

So the graph is reflected across x axis

Robin’s graph is a reflection of Giselle’s graph over the x-axis
