The vertex of the graph of a quadratic function is (–2, –9) and the y-intercept is (0, –5). which of the following is the equation of the function? a. y = x2 +10x + 2 b. y = x2 +10x – 2 c. y = x2 – 2x – 5 d. y = x2 + 4x – 5

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1

If f(x) = 4 - x2 and g(x) = 6x, which expression is equivalent to (g-f)(3)? 06-3-(4 + 3)2 06-3-(4-33 6(3) - 4 +32 6(3) -4 -32
