Question

HELP, UNIT TEST

y=(x-2)(x+6)


what are the x intercepts?
what is the vertex?

Answer 1

`{Minimum}\space\left(-2,\:-16\right)`minimum (-2, -16)

Explanation:

`y=\left(x-2\right)\left(x+6\right):\\`

`a=1,\:m=2,\:n=-6`

`x_v=(m+n)/(2)`

`x_v=(2+\left(-6\right))/(2)`

Plug in xv = -2 to find the value

`y_v=-16`

`\left(-2,\:-16\right)`
`{Minimum}\space\left(-2,\:-16\right)`

`{Minimum}\space\left(-2,\:-16\right)`minimum (-2, -16)

`\mathrm{Minimum}\space\left(-2,\:-16\right)`
