Y = 3x^2 + 18x + 30
a = 3, b = 18, c = 30

h = -b/2a = -18 / 6 = -3
<span>k = (4ac – b^</span>2<span>) / 4<span>a = (360 - 324)/12 = 36/12 = 3
</span></span>
vertex (h, k) = (-3,3)


answer
(-3, 3)

Answer:

f(-2) = 0

f(1) = 12

f(2) = 5

Step-by-step explanation:

f(-2) will lie in the function f(x) =x^2 - 4

\therefore f( - 2) =  {( - 2)}^{2}  - 4 = 4 - 4 = 0

f(1) will lie in the function f(x) =2x^2 +10

\therefore f(1) = 2 {(1)}^{2}  + 10 = 2 + 10 = 12

f(2) will lie in the function f(x) =5

\therefore f(2) = 5
