Answer:
make the y int -4 because it passes through (0,-4). to make perpendicular, apply same slope to new equation but change sign
equation:
3x -4
An even function can be reflected about the y axis and map onto itself
example: y=x^2
an odd function can be reflected about the origin and map onto itself
example: y=x^3
a simple test is the following
if f(x) is even then f(-x)=f(x)
if f(x) is odd then f(-x)=-f(x)
so
even function
subsitute -x for each and see if we get the same function
remember to fully expand these
g(x)=(x-1)^2+1=x^2-2x+1+1=x^2-2x+2 is the original one
g(x)=(x-1)^2+1
g(-x)=(-x-1)^2+1
g(-x)=(1)(x+1)^2+1
g(-x)=x^2+2x+1+1
g(-x)=x^2+2x+2
not same because the original has -2x
not even
g(x)=2x^2+1
g(-x)=2(-x)^2+1
g(-x)=2x^2+1
same, it's even
g(x)=4x+2
g(-x)=4(-x)+2
g(-x)=-4x+2
not the same, not even
g(x)=2x
g(-x)=2(-x)
g(-x)=-2x
not same, not even
g(x)=2x²+1 is the even function
Answer:
greater then
Step-by-step explanation:
Answer:
The length is 22.5 and the width is 19.5
Step-by-step explanation:
2L + 2W = P
\/
2L + 2W = 84
\/
W + 3 + W + 3 + W + W= 84
\/
4W + 6 = 84
\/
4W = 78
\/
W = 19.5 L = 19.5 + 3 = 22.5
I hope this helps, have a nice day! :D
