Select the equation of the quadratic function that models the relationship between time and height for an object thrown into the air, as presented in the parabola above. Question 11 options: A) ƒ(x) = –(x – 2)2 + 7 B) ƒ(x) = (x – 2)2 + 7 C) ƒ(x) = –(x + 2)2 + 7 D) ƒ(x) = (x + 2)2 + 7

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x

step-by-step explanation:

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
