1<=x<=4
0<=x<=3

Answer 1

please help

Answer 2

oh my did i hear the f word? XD
before we start did you make a mistake in the equation? is there supposed to be a t next to the 94?

Answer 3

yes

Answer 4

will give medal

Answer 5

ok first we need to find out where the maximum point is
the general equation to quadratics equations like this is y=Ax^2+bx+c
we'd use x=-b/2a to find the x coordinate of the maximum point
you following me?

Answer 6

yes

Answer 7

ok ill set it up for you then you can do the simplification
\[X=\frac{ -94 }{ 2\times-16 }\]
solve for x please

Answer 8

how?

Answer 9

you divide -94 with (2 times -16)
you might need a calculator

Answer 10

-2.9375?

Answer 11

Answer 17

am I correct I think its the last one

Answer 18

please I will be your fan can you help me

Answer 19

no
if it's the last one then it's stating that at x=0 is the maximum and that it ends at x=3

Answer 20

so the first one?

Answer 21

yes
