for y = x^2 + 3, from Mth 272 studenty=-2^2+3= -4+3
@&
You have evaluated the function at the specified points. However you did not always do your arithmetic correctly.
y = x^2 + 3.
So if x = -2, you would get
y = (-2)^2 + 3,
not
y = -2^2 + 3.
The reason:
In the expression
y = x^2 + 3,
it is clear that the value of x is to be squared. However, by order of operations, -2^2 requires that you square 2, then apply the negative sign to get -4.
If you square -2 you get +4, not -4.

y=-1^2+3= 2
y=0^2+3=3
y=1^2+3=4
y=2^2+3=7
y=-1 x=-2
y=2 x=-1
y=0 x=3
y=1 x=4
y=7 x=2 "
