Let f(x) = 5x - 4 and g(x) = x^2- 1. Find (g•f)(0).

Step-by-step explanation:

So we have the two functions:

And we want to find:

This is the same as:

So, find g(0) and f(0):

g(0):

Substitute 0 into g(x):

Square:

Subtract:

And f(0):

Substitute 0 into f(x):

Multiply:

Subtract:

So, our equation is now:

Multiply:

So, our answer is 4.

And we're done!

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.
