Answer:
(g o f)(x) = 
(not simplified)
Step-by-step explanation:
(g o f)(x) = g(f(x))
g(x) = 
f(x) = 
g(f(-5)) = g(
= 
= 
g(-170) = 
=
Sqrt(-2), can be written as i * sqrt(2). Thus, our answer is x - i sqrt(2).
Answer:
z = (-b + 17)/(a+4)
Step-by-step explanation:
If in terms of a and b, then
az - 17 = -4z - b
z(a-4) = -b+17
z = (-b + 17)/(a+4)

Answer:
see explanation
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
y = x² - 6x + 3
To complete the square
add/subtract ( half the coefficient of the x- term)² to x² - 6x
y = x² + 2(- 3)x + 9 - 9 + 3
= (x - 3)² - 6 ← in vertex form
• If a > 0 then vertex is a minimum
• If a < 0 then vertex is a maximum
Here a = 1 > 0, thus
(3, - 6 ) is a minimum
