Answer:
It means that you have a function that every time you input a value of x gives you 3 . If x=45 then y=3 ...if x=−1.234 then, again, y=3 and so on!
Step-by-step explanation:
Answer:

Step-by-step explanation:
Let us assume that,
x represents the number of sq. yards of fabric and
y represents price of the fabric.
As the unit price of the fabric i.e cost per sq. yard of fabric is $1.25, so for each number of sq. yard of fabric, the cost for that much of fabric will be multiple of 1.25 of that number.
i.e 
Here, the rate of change is 1.25. So for each increase in x, the amount of increase in y is 1.25
The table along with the graph have been attached below.
f(x)=4x^3 - 6x^2 + 2x - 5
f(-2)
Replace X with -2:
4(-2)^3 - 6(-2)^2 + 2(-2) - 5 =
Calulate the powers:
4(-8) - 6(4) +(-4) -5=
Multiply:
-32 - 24 -4 -5=
Subtract
-65
