Answer:

<h2>(f\circ \: g)(x) =  {3x}^{2}  - 6</h2>

Step-by-step explanation:

f(x) = x - 5

g(x) = 3x² - 1

To find (fºg)(x) substitute g(x) into f(x) that's for every x in f (x) replace it with g (x)

That's

<h3>(f\circ \: g)(x) = 3 {x}^{2}  -1 - 5</h3>

We have the final answer as

<h3>(f\circ \: g)(x) =  {3x}^{2}  - 6</h3>

Hope this helps you

A line has a slope of -3 and y-intercept of 2.
Pie

AnswA line can be written in the form y = mx + b where m is the slope and b is the y intercept.

Since the slope is given as 4, the equation will be y = 4x + b

Plugging in the point (2,1) to the equation we get 1 = 4(2) + b or 1 = b + 8

Solving for b gives b = -7 so the equation will be y = 4x - 7er:
