Identify the vertex and axis of symmetry of 8x $y=-x^(2) +8x-12$

Answers

$y=-x^2+8x-12\ny=-(x^2-8x)-12\ny=-[(x^2-8x+16)-16]-12\ny=-[(x-4)^2-16]-12\ny=-(x-4)^2+16-12\ny=-(x-4)^2+4$

Factor the minus or negative off the -x²+8x and don't do anything with -12

Find the number that can complete the square, for x²-8x, it'd be +16.

Just think of debt, you borrow, you have to give back. You borrow +16 then you have to give 16 out so you write -16 out of x²-8x+16 but still inside the bracket.

Distribute the minus/negative inside the bracket as you get -(x-4)²+16-12 because negative multiply negative and you get positive

Then you get y=-(x-4)^2+4

Because a<0, it's inverted parabola as shown below.

therefore, the vertex is at (4,4) or (-(-4), 4) because the vertex is at (-h,k) and h is -4 that means -h = 4

axis of symmetry is -b/2a, our b is 8, -b = -8 and 2a = 2(-1) so -8/-2 = 4 (From the standard form)

therefore, axis of symmetry is 4
