math help anyone?..

[gotchi_grl]

sorry kiddos. only algebra people.

mkay, so we're doing arrow notation.

number 5 says:

find the range of each function.

5. G: a -> 4a squared, d={-1, 0, 1}

agh i need help!

i keep getting {-1, 15}.

but that's not the answer, i checked in the back of the dern book!!

help would be greatly appreciated.

College student here. If I understood the notation (arrow? do you mean inequalities?), I'd be better able to help you out. Do you mean to say that a is greater than 4a squared? PM me sometime! I'd love to delve back into algebra after years of doing excruciating calculus.

I've skipped this grade, but I think the solution is {0,4]

You substitute a by -1, 0 and 1.

4(-1)(-1) = 4 x 1 = 4

4(0)(0) = 0

4·1·1= 4

Unless it is (4a) squared. In which case I think it is:

-4 x -4 = 16

0 x 0 = 0

4 x 4 = 16

{0, 16}

That just looks like a bunch of random numbers to me
