Question

which equation represents a linear function?
    A.)y=-x^2-4
    B.)-3x^2+1=y
    C.)y=x^2
    D.)x+2=y

anonymous · Answer

a first degree polynomial. so the x has a power of 1

anonymous · Answer

constant slope

anonymous · Answer

mmmmmm still confused on this question??....

anonymous · Answer

A  linear function will be in the format y=mx+b

anonymous · Answer

yes, that is correct. The highest degree of polynomial for a linear function is to the power of 1.

anonymous · Answer

oka.. so its B right?

anonymous · Answer

x^2 is to the power of 2
x^1 is to the power of 1 but we don't actually write the power to 1 but rather just x.

anonymous · Answer

nope, not b because it has x^2 so it's to the power of 2.

anonymous · Answer

OH OKA.. HOLD ON LET ME SEE WHICH ONE IT IS SO ITS IN CAPS FORGOT TO TAKE OFF CAPS

anonymous · Answer

so the only one left with out a power of 2 is d.) nno i think im still wrong

anonymous · Answer

hello anybody here?

anonymous · Answer

really?

anonymous · Answer

yes

anonymous · Answer

it is d.

anonymous · Answer

Ok so my last option would be d

anonymous · Answer

thats what me thought lol skittles luves you lol

anonymous · Answer

x+2=y      you can see the power of x is 1 because x^1 is the same thing as x.

anonymous · Answer

even if you rearrange it into y=-x+2   the form of y=ax+b
you can see the power of x is still one, therefore it is linear.

anonymous · Answer

and like  JayDs said you would be looking for a constant slope with a degree of x.

anonymous · Answer

thank yall an js my name is skittles an i luv you guys for helpin me
