8) y intercept is (0, 15) or 15

   slope is 10 (the y intercept represents how much it would cost to open an online gaming account and the slope represents how much each game costs after you open an online gaming account, including the $15 fee to open the account)

9) y=10x+15

10) you can look at the graph where it says number of games and go to 6 and go up until you reach the line and look at the side where it says cost (dollars) and then you will see that 6 games cost $75

What are the vertical asymptotes of the function f(x) =5x+5/x2 + x-2
katen-ka-za [31]

let's recall that the vertical asymptotes for a rational expression occur when the denominator is at 0, so let's zero out this one and check.

\bf \cfrac{5x+5}{x^2+x-2}\qquad \stackrel{\textit{zeroing out the denominator}~\hfill }{x^2+x-2=0\implies (x+2)(x-1)=0}\implies \stackrel{\textit{vertical asymptotes}}{ \begin{cases} x=-2\\ x=1 \end{cases}}

What is the value of f^-1(0)?<br><br><br><br> Please help! It’ll be greatly appreciated!
Leya [2.2K]

Answer:

f^{-1}(0)=6

Step-by-step explanation:

So, we have the graph y=f(x).

And we want to find:

f^{-1}(0)

Remember that the inverse of a function is simply the x-values and y-values swapped. To see this, let's let our inverse equal y:

f^{-1}(0)=y

This means that we have the point:

(0,y)

So, to find our solution, we will swap the x- and y-coordinates. This gives us:

(x,0)

So, simply need to find the x-coordinate such that y is 0.

From our graph, we can see the point (6,0). In other words:

f(6)=0

So:

f^{-1}(0)=6

And we're done!
