PLEASE HELP ME!!!!!!!

Mathematics
1 answer:
ExtremeBDS [4]3 years ago
4 0

Answer:

C

Step-by-step explanation:

First, since y is less than or equal to x+4, that shows that it must be either C or D, because both of those regions are below the line x+4.

Next, since y is more than or equal to -3/2x-1, this shows that C is the answer.

We can also check by seeing the graph when x = 0. Notice that y = 0 is in the region C, and notice that 0 satisfies the 2 inequalities, because -1≤0≤4.

Still confusing to me!!!!
juin [17]

Answer:

  (a)  2(x -a)

  (b)  4x +2h

Step-by-step explanation:

Fill in the function arguments and simplify.

a.

\dfrac{f(x)-f(a)}{x-a}=\dfrac{(2x^2-7)-(2a^2-7)}{x-a}\\\\=\dfrac{2x^2-7-2a^2+7}{x-a}=\dfrac{2(x^2-a^2)}{x-a}\\\\=\dfrac{2(x-a)(x+a)}{(x-a)}=2(x+a)

__

b.

\dfrac{f(x+h)-f(x)}{h}=\dfrac{(2(x+h)^2-7)-(2x^2-7)}{h}\\\\=\dfrac{2x^2+4xh+2h^2-7-2x^2+7}{h}=\dfrac{4xh+2h^2}{h}\\\\=4x+2h
