Answer:
See attached picture.
Step-by-step explanation:
h(x) has two functions in it. It has y = x and y =-x. Both have a slope of 1 or -1 and are diagonal lines. This means only 2 graphs of the four choices are possible answers.
Notice that y = -x has an interval that is greater than or equal to. This means it is marked with a closed or filled in dot at its start. This means choice B is the correct choice.
Answer: OPTION B.
Step-by-step explanation:
Given the equation
you can find an equivalent equation by simplifying it.
You need to remember the multiplication of signs:

Now you can apply the Distributive property:

Simplifying the equation, you get:

You can observe that this equivalent equation matches with the equation provided in option B.
First of all, since all powers of x in this function are even, the entire function is even. Thus, using -x as input doesn't change the function. Thus, f(-x)=2x^2-4.
