Answer:
vertex = (- 10, - 10 )
Step-by-step explanation:
The equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square.
Given
h(x) = x² + 20x + 90
add/subtract ( half the coefficient of the x- term )²
h(x) = x² + 2(10)x + 100 - 100 + 90
= (x + 10)² - 10 ← in vertex form
with (h, k ) = (- 10, - 10 )

Step-by-step explanation:
Answer:
Domain = R- {0,4}
Step-by-step explanation:
In order to function (f*g)x to be defined , the Denominator must not be equal to zero.
Hence
x ≠ 0
(x-4) ≠ 0 ⇒ x≠4
Hence (f*g)x is defined for all values of x except 0 and 4
Hence Domain = R- {0,4}
