The number in the parenthesis is the X value and they are looking for what the Y value is at that specific X.
So when you look at f(-2), find the Y value where the line crosses.
At X-2, the line crosses Y at -2
At X = 2, the line crosses at Y = 2
At X = 4, the line crosses at Y = 1
The answer is -2,2,1
F(x)=x(3x+5)
or
f(x)=3x²+5x
Here the domain in general is: -∞<x<∞
But the length of the rectangle cannot be negative, therefore the domain is all real numbers greater than zero.
Option D is correct.
Answer
-21x + 5y - 7

Step-by-step explanation:
Answer:
At this point just choose a mean thats half of the value
First calculate the area of the pool, which is 15 x 15, = 225 sq meter,
and just multiply the cost for each sq meter by the area,
17.5 x 225
therefore the cost will be $3937.5
