Answer:
f(g(x)) = (5x)^2 = 25x^2
Step-by-step explanation:
If f(x) = x^2 and g(x) = 5x, then
f(g(x)) = (5x)^2 = 25x^2
Answer:
John Muir
John Muir was an American naturalist born in Scotland on April 21, 1838. Step-by-step explanation:
Notice that we can simplify both numerator and denominator of our rational function. In the numerator we have a quadratic expression of the form

. To to simplify it, we are going to find tow numbers that add to 2 and multiply to -8; those numbers are 4 and -2.

In the denominator we have a difference of squares:

Now we can rewrite our function:

From the simplified form of our rational function we can infer that its graph has two vertical asymptotes at

and
We can conclude that the graphic of our rational function is:
