Giselle graphs the function f(x) = x^2. Robin graphs the function g(x) = –x^2. How does Robin’s graph relate to Giselle’s?
2 answers:
Robin's graph of the function is the reflection of Giselle’s graph over the x-axis.
You can think in two ways:
1. For the function y=f(x), the sign minus before f(x) change the positive values of y into negative values. For example, f(2)=4 and g(2)=-4. This means that graphs of f(x) and g(x) are symmetric across the x-axis.
2. You can simply construct the table of values
and plot both graphs on the coordinate plane. From this diagram it is seen that graphs are symmetric over x-axis and Robin’s graph is a reflection of Giselle’s graph over the x-axis.

Answer:
You can not divide by zero.
The inequality is equivalent to - 20.2 > 0 which is false.
Step-by-step explanation:
We can not divide both sides by zero, because if we divide both sides by zero, then the inequality becomes
⇒ - ∞ > y, which is not possible.
Again, the given inequality is - 20.2 > 0 × y.
We have to multiply y with zero and a product of zero with any term is also zero.
Hence, the inequality becomes - 20.2 > 0.
Therefore, the inequality is equivalent to - 20.2 > 0 which is false. (Answer)
