Even function neither even nor odd odd function both even and odd f(x)=x2+3

For a function to be even, it must be symmetrical to the y-axis.

Although we have f(x) = x² + 3, let's just imagine the parent graph

f(x) = x² which has a y-intercept of 0 and is of average width.

This is symmetrical about the y-axis, but we want to know

whether or not f(x) = x² + 3 is symmetrical to the y-axis.

We can shift the parent graph f(x) = x² by adding

a constant, 3, to give us f(x) = x² + 3.

Translating the parent up or down will always result

in an even function because it will always be symmetrical.

step-by-step explanation:

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
