i have no idea I am given what is typed above with the statement at the begining of the assignment that say simplify or solve...
so does it seem like they want you to find what f(0) and f(2) are?
that would be my guess
are you familiar with what a function is?
i probably would be but this is my first math class in almost 9 years
basically a function is a machine that you feed an x-value, and it spits out a y-value
so whatever number you put into the function machine, it does what it does and you get some output
anyways, it is asking you to feed 0 and 2 into the function and see what comes out. so you need to plug those values in for x and compute the result
so instead of it saying -3x^2 I should put the 0 where that x is so it would read (3)(0)^2 ???
right, to find f(0), put a 0 wherever you see an x and keep everything else the same
so my answers would be 5 and 33?
5 looks right, but how did you get 33?
\[(-3(2))^{2} -4(2) +5\]
are those outer parentheses in the first part in the original equation, or did you add them?
I added them
with a question like this you need to make sure to just plug in the number to the exact equation and not change it in any way. do you see why the extra parentheses make a difference?
i have to go in a second, but the -3 shouldn't be squared, the exponent only applies to x
