is continuous over its domain, all real
.
Meanwhile,
is defined for real
.
If
, then we have
as the domain of
.
We know that if
and
are continuous functions, then so is the composite function
.
Both
and
are continuous on their domains (excluding the endpoints in the case of
), which means
is continuous over
.
Answer:
20 % discount
Step-by-step explanation:
Lilian got 4 dollars off of the original price (20 - 16 = 4 )

Answer:
x=30
Step-by-step explanation:
if 30 x 4 = 120 amd 2 = 30 = 60 then 60+120=180
Y - y₁ = m(x - x₁)
y - 2 = 4(x - 7)
y - 2 = 4(x) - 4(7)
y - 2 = 4x - 28
+ 2 + 2
y = 4x - 26
