What is the inverse of the function y= x^2-12
aalyn [17]

Answer:

y=\sqrt{x+12}

Step-by-step explanation:

To find the inverse of a function, what I like to do is to switch the places of x and y, and then try to isolate y again like so:

x=y^2-12

x+12=y^2

y=\sqrt{x+12}

Hope this helps!

Write an equation of the parabola in vertex form. <br><br>No LINKS!!!! ​
marissa [1.9K]

9514 1404 393

Answer:

  y = -16x² +180

Step-by-step explanation:

The vertex appears to be the high point of the graph, (0, 180). Then the vertex form equation is ...

  y = a(x -0)² +180

The value of 'a' can be found using the other given point. Substituting for x and y, we have ...

  164 = a(1 -0)² +180

  -16 = a

Then the complete simplified vertex form equation is ...

  y = -16x² +180
