Question

how do I evaluate the function 3x^2/3 -2 at -1

Answer 1

plug -1 in

Answer 2

So will it then become y= 3(-1^2/3) -2 OR y=-4^2/3 -2

Answer 3

because of order of operations, you should first raise the -1 to the exponent and then multiply by 3 and then subtract 2

Answer 4

how do evalute 2^5/2 – 2^3/2

Answer 5

or actually, what I said is wrong

Answer 6

you need to do order of operations

Answer 7

so first you do everything in parentheses (which there are none)
then exponents
then multiplication and division
then addition and subtraction
