Step-by-step explanation:
f°g=




if the denominator is zero the number is undefined which makes it not in the domain of the function
set
equal to 0
the values for x is 0 or 6
so the only value that is not in the domain of f°g is 0 and 6
Hope that helps :)
(h,k) is the vertex
b/2a is the line of symmetry
a > 0 parabola opens upward, vertex is a minimum
a < 0 parabola opens downward, vertex is a maximum

Answer:
y =
x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (4, 5) ← 2 points on the line
m =
= 
The line crosses the y- axis at (0, 2 ) ⇒ c = 2
y =
x + 2 ← equation of line
Answer:
x>22
Step-by-step explanation:
Solve the inequality:
-3x<-14-52
-3x<-66
x>22
( You have to switch the sign because you are dividing by a minus)
