Quiz 3.2 - Vertex Form & Inverses

Match the functions with their inverses.

Hint: words go with words and functions (y=...) go with functions.

Find the inverse of the function.

y=\sqrt{x+2}-1

Use vertex form, y=..., no spaces.

Find the inverse of the function.

y=\frac{1}{2}\sqrt{x-3}

Use y=... form, no spaces.

Find the inverse of the function.

y=-3\sqrt{x}+6

Use y=... form, no spaces.

Find the inverse of the function.

y=\frac{1}{2}x^2

Use y=... format, no spaces.

Find the inverse of the function.

y=(x-3)^{2} + 5

Use y=... format, no spaces.

Find the inverse of the function.

y=(\frac{1}{2}x+1)^{2}

Use y=... format, no spaces.

Put y=x^{2} - 4x -3 in vertex form.

As a reminder, vertex form of a quadratic: y=A(x-h)^{2}+k. Desmos will help you.

The question #6 is in vertex form. Use it and its graph to help you.

Use y=... format, no spaces.

Put y=-x^{2} + 6x in vertex form.

Use y=... format, no spaces.

Put y=2x^{2} + 4x+2 in vertex form.

Use y=... format, no spaces.

Put y=x^{2} + 3x-1 in vertex form.

Use y=... format, no spaces. Use fractions, not decimals.
