Answer:

Option B is correct

Step-by-step explanation:

Given: h(x)=\frac{1}{x^2+1} is the result of the composition f(g(x)).

Also, g(x)=x^2+1

To find: f(x)

Solution:

Take f(x)=\frac{1}{x}

Now check whether h(x) is equal to f(g(x)) or not.

First find f(g(x))

f(g(x))=f(x^2+1)=\frac{1}{x^2+1}

Also, h(x)=\frac{1}{x^2+1}

Therefore,

h(x)=f(g(x))

So,

Option B is correct

Mashutka [201]
So, you basically plug the values into the formula you have been given. D divided by T gives you the average speed.
We know the distance D is 145 miles and the Time T is 2.5 hours.

So, 145/2.5=58

Therefore, the cars average speed was 58 miles / hour
