Answer:
Step-by-step explanation:
Subtracting 4x from both sides of the inequality.
Simplifying the inequality.
If f(x) = x^2 - 4x + 3, and the domain is {-2, 0, 1}, what is the range?
1 answer:
Evaluate the function at the three values of the range and see what you get. The appropriate choice is ...
... D) {15, 3, 0}
_____
Evaluation can sometimes be simpler if you rearrange the function to a form called "Horner's form."
... f(x) = (x -4)x +3
Then the evaluation looks like (for x=-2) ...
... f(-2) = (-2-4)(-2)+3 = (-6)(-2) +3 = 12 +3 = 15
This is sufficient to identify D as the answer of choice.

Answer:
(0,0) is among the solutions
Step-by-step explanation:
The given inequality is
A solution to this inequality is any ordered pair that satisfies the inequality.
Let us check for x=0 and y=0
We substitute to get:
....This is true.
Therefore (0,0) is a solution to the given inequality.
There are infinitely many solutions.
