(4,7)
Step-by-step explanation:
The equation for a parabola can be written as
y = a (x-h) ^2 + k where (h, k) is the vertex
given f (x) = (x-4) ^2+7
The vertex is (4,7)

vertex is 4
Step-by-step explanation:
y = (x-4) ^2 + 7
(x-4) (x-4)
x * x = x^2
x * - 4 = - 4x
-4 * x = - 4x
-4 * - 4 = 16
x^2 - 8x + 16
y = x^2 - 8x + 16 + 7
y = x^2 - 8x + 23
a b c
formula to find vertex: - b / 2a
= - b / 2a
= - (-8) / 2 (1)
= 8 / 2
= 4
vertex = 4
(what i did was work out the exponent outsite the parentesis then i got the equation i wanted, and from that equation i used the formula to find the vertex and i just plugged the numbers of the equation into the formula and work it out)
