Question

what is the relative maximum of f(x)=−3x^2+5x+2 (the relative minimum does not exist) please help!!!!

Answer 1

differentiate it and equate to zero

Answer 2

you will get the value of x where it is maximum and that is 5/6

Answer 3

Substitute the value of X in f(x)

Answer 4

plug in -2 for every x within the equation f(x)
so
f(-2)=3 (-2^2) + 5 (-2) -2
=3 (4) +(-10) -2
=12-10-2
= 0

Answer 5

Wait so what does that mean? It says the answer is supposed to be (x,y)

Answer 6

is it (5/6,49/12)?

Answer 7
