Have I been solving these equations correctly?

14)

2(-3)² => 2(-3)(-3) => 2*9 = > 18

27+18-11 => 27 + 7 = > 34.

16)

$\bf p(x)=\cfrac{x^2-4}{2x+1}\implies p(-8)=\cfrac{(-8)^2-4}{2(-8)+1}\implies p(-8)=\cfrac{64-4}{-16+1} \\\\\\ p(-8)=\cfrac{60}{-15}\implies p(-8)=-4$

17)

$\bf h(x)=3\cdot 9^x\implies h(-2)=3\cdot 9^{-2}\implies h(-2)=3\cdot \cfrac{1}{9^2} \\\\\\ h(-2)=\cfrac{3}{9^2}\implies h(-2)=\cfrac{3}{81}\implies h(-2)=\cfrac{1}{27}$

Given f(x)= square root x and g(x) = lxl, which is the graph of (fog)(x)

marin [14]

Answer:

drawing the graph of $f(g(x))=\sqrt{|x|}$

The graph is attached in the images below.

Option A is correct option.

Step-by-step explanation:

We are given:

$f(x)=\sqrt{x}$ and $g(x)=|x|$

We need to find graph of (fog)(x)

We know that (fog)(x)= f(g(x))

Placing x=g(x) i,e x=|x|

$(fog)(x)= f(g(x))\\f(g(x))=\sqrt{|x|}$

Now, drawing the graph of $f(g(x))=\sqrt{|x|}$

The graph is attached in the images below.

Option A is correct option.

Find the equation of the line.<br> Use exact numbers.

iren2701 [21]

Answer:

y=3/4x -2

Step-by-step explanation:

I know the last box has a plus sign in front of it but it's still -2 since the y- intercept is at -2. It's the same thing but I just wanted to make sure you knew that in the last box, you still put -2.

Sorry if what I just said above is confusing, i don't know how to explain it better...
