Which function has a vertex at the origin?
f(x) = (x + 4)2
| Of(x) = ffx – 4)
f(x) = R7– 4)(x +
o f(x) = x²

Suppose y varies directly with x. write a direct variation equation that relates x and y. then find the value of y when x=12 y=7 when x=3

The point a is at –2 and the point b is at 7. marissa would like to divide this line segment in a 4: 3 ratio, and she would like to use the formula x = (x2 – x1) + x1. what values should she substitute into the formula? a = a + b = x1 = x2 =
