Write the equation for a parabola with the vertex
at (-1, 3) and the equation of the directrix y = 1.
(x - 1)2 = (y + 3)
(x + 1)2 = 8(y - 3)
(x - 1)2 = 8(y + 3)
(y - 3)2 = 2(x + 1)

Match each graph with the correct equation from the equation bank. not all equations will be usef

Identify which functions are linear or non-linear. a. f(x) = x2 + 1 b. f(x) = 2x + 5 c. f(x) = x 2 + 3 d. f(x) = 3 x + 7 e. f(x) = 4x + 10 2 - 5
