Answer:
y = (x + 9)² + 9
Step-by-step explanation:
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
given a parabola in standard form : ax² + bx + c : a ≠ 0
the the x-coordinate of the vertex is
= - 
y = x² + 18x + 90 is in standard form
with a = 1, b= 18 and c = 90
= - 
= - 9
to find the corresponding y-coordinate substitute x = - 9 into the equation
y = (- 9)² + 18(- 9) + 90 = 81 - 162 + 90 = 9
⇒ y = (x + 9)² + 9 ← in vertex form

Answer:
The function f(x) is shifted horizontally left by 2 units.
Step-by-step explanation:
Given the function is g(x) = x² + 3.
Now, f(x) = g(x + 2) = (x + 2)² + 3
Therefore, for a certain value of y, the x-value of function g(x) will be 2 units more than that of function f(x).
Therefore, the function f(x) is shifted horizontally ( the x-axis is the horizontal axis) left by 2 units compared to the function g(x). (Answer)
