Question

Y-7 = (12-x)2 in vertex form

Answer 1

y = -2x + 31

Explanation:

Vertex form a parabola refers to a place or a point where it turns. It takes the form of;

y = mx + c

From our question, we are supposed to convert the equation y-7 = (12-x)2 into vertex form.

To begin, open the brackets on the RHS;

y - 7 = 24 - 2x.

Then move -7 to the RHS which becomes the positive.

Y = 24 - 2x + 7

= 31 - 2x

Convert it to the form y = mx + c.

y = -2x + 31

This is the vertex form, y = -2x + 31.

Note:

• For a standard form/quadratic, the equation has to be in the form ax² + bx + c = y
