Which graph represents the function. H(x)=

scZoUnD [109]

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.

Question 1 (1 point)

Natalija [7]

Answer: OPTION B.

Step-by-step explanation:

Given the equation $48=-8(\frac{3b}{4}+2)$ you can find an equivalent equation by simplifying it.

You need to remember the multiplication of signs:

$(-)(-)=+\\(+)(+)=+\\(+)(-)=-$

Now you can apply the Distributive property:

$48=\frac{(-8)(3b)}{4}+(-8)(2)\\\\48=\frac{-24b}{4}-16$

Simplifying the equation, you get:

$48=-6b-16$

You can observe that this equivalent equation matches with the equation provided in option B.

The function f is defined by f(x)=2x^2-4.<br> Find f(-x)

Vedmedyk [2.9K]

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.
