Good morning ☕️
Answer:
<h2>x² + 7x - 7</h2>
Step-by-step explanation:
f(x)=7x-3 and g(x)=x²-4
(f+g)(x) = f(x) + g(x) = 7x - 3 + x²- 4
= x² + 7x - 7

so is this the formula you trying to get an an see for?
The first thing we must do for this case is to find the equation of the line.

We have then:

We choose an ordered pair:

Substituting values:
From here we conclude:
Intersection with y:
We evaluate x = 0 in the function:
Slope of the line:
Point (-2, -5):
We evaluate the value of x = -2 and the value of y = -5

The equation is satisfied.
Point (8, 0):
It is part of the table, therefore belongs to the line.
Answer:
The slope is 1/2
The y-intercept is -4.
The points (-2, -5) and (8, 0) are also on the line.
