The function f is given in three equivalent forms. Which form most quickly reveals the vertex?
Choose 1
A
f(x) = -3(x + 1)(x - 5)
B
f(x) = -32? + 12x + 15
f(x) = -3(x - 2)2 +27
What is the vertex?

The suare root of 9x plus 7 plus the square rot of 2x equall to 7

If the endpoints of the diameter of a circle are (8, 6) and (2,0), what is the standard form equation of the circle? a) (x + 5)2 + (y + 3)2 = 18 (x + 5)2 + (y + 3)2 = 3.72 (x - 5)2 + (y - 3)2 = 18 d) (x - 5)2 + (y - 3)2 = 32

Me! i will mark brainliest! i don't get polynomials and all that other stuff. so this question is really hard. multiply and simplify.(x - 4) (x^2 – 5x – 6)show your
