Given:

$f(x)=\frac{x+2}{x^2+2x-8}$

find the denominator:

$x^2+2x-8$

$(x+4)(x-2) = y$

Find the x value:

$x-2=0\\x=2$

$x+4=0\\x=-4$

Your answer would be D:

x = -4, 2

How do you Graph y-3=1/3(x+1)

jekas [21]

Answer:

You can find the point of intersection of the line with the y-axis and the the point of intersection of the line with the x-axis. See the graph attached.

Step-by-step explanation:

Find the intersection with the y-axis. Substitute $x=0$ into the equation and solve for y:

$y-3=\frac{1}{3}(x+1)\\\\y-3=\frac{1}{3}(0+1)\\\\y-3=\frac{1}{3}(1)\\y=\frac{1}{3}+3\\\\y=\frac{10}{3}$

$y$ ≈3.33

Find the intersection with the x-axis. Substitute $y=0$ into the equation and solve for x:

$y-3=\frac{1}{3}(x+1)$

$0-3=\frac{1}{3}(x+1)\\(-3)(3)=x+1\\-9-1=x\\x=-10$

Now, you know that the line passes through the point (0,3.33) and (-10,0). Now you can graph the function. (Observe the graph attached)

Pani-rosa [81]

Answer:

3,000,000,000

Step-by-step explanation:

3 x 10^9 = 3 x 1,000,000,000 because if it were 10^1, then there would be 1 zero. Same thing for this. Since it's 10^9, there will be 9 zeroes.
