Answer:
The product of (x-3) and (x+7) is x² + 4x - 21
Step-by-step explanation:
The product of (x-3) and (x+7) is x² + 4x - 21
The product of (x - 3) and (x + 7) can be found as follows:
(x - 3)(x + 7)
open the bracket by multiplying
Therefore,
x(x) +x(7) - 3(x) - 3(7)
x² + 7x - 3x - 21
combine like terms
x² + 4x - 21

Answer:
Graph (2).
Step-by-step explanation:
Given question is incomplete: Find the complete question in the attachment.
Given : f(x) = -
g(x) = - 1
To find : The graph showing f(x) = g(x)
If the given functions f(x) = g(x)


= 1
x = -2
That means both the functions have the same value at x = -2
f(-2) = g(-2) = -1
In other words, both the lines will intersect at a point (-2, -1).
From the given graphs,
Graph number (2) shows the required results.
A straight line g(x) = -1 parallel to x- axis and another straight line f(x) =
, intersect each other at (-2, -1).
Therefore, Graph (2) will be the answer.
