Which equation is the inverse of y = x2 – 36?
2 answers:
Answer:
The given equation of the curve is
y= x² - 36
To find it's inverse we have to convert y in terms of x.
So, adding 36 to both sides of equation
→ y + 36=x² -36 + 36
→ y + 36 = x²
→ x² = y+ 36
→ x =
Now, to find inverse you can replace x by y, so by replacing x by y, the above equation becomes
y =
Second option is correct.

Hello!
The slope intercept form is y=mx+b, where m is the slope and b is the y-intercept.
First, let's find the y-intercept. This is where the line hits the y-axis. Therefore, it hits at 4 on the y-axis, so our y-intercept is 4.
To find the slope, let's find 2 points on our line. Let's use (0,4) and (2,5). We divide the difference in the y-values by the difference in the x-values as shown below.
Therefore, our slope is 2.
Now we plug these values into our equation.
y=2x+4
I hope this helps!
