You have to equal them together, then solve. plug in x to AM and you get the answer.
the answer is 20
We are given
f(x)=
g(x)=
\to find f o g, replace all the x in f(x) with g(x)
= Simplify by taking least common denominator and reciprocal.
Taking the least common denominator, we get
Taking reciprocal, we get
Simplifying the expression, we get
To find the domain of a composite function, we need to find the domain of f o g and the first function i.e g(x)
To find the domain of f o g, equate the denominator to 0
It means, domain is all real numbers except
Domain of g(x) is all real numbers except
combined domain is
Answer:
y = - 0.5x
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 ) = (- 4, 2) and (x₂, y₂ ) = (2, - 1) ← 2 points on the line
m = = = = - 0.5
The line crosses the y- axis at (0, 0 ) ⇒ c = 0
y = - 0.5x + 0 . that is
y = - 0.5x
