Which function has a vertex at the origin?
EOF
Of(x) = (x + 4)2
Of(x) = x(x - 4)
f(x) = (x – 4)(x + 4)
O f(x) = x²

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars
