Question

i need to use reasoning to answer this and also need to find x intercept and y intercept and maxium and minimum please help f(x)=x(x+6)

Answer 1

plug zero in for x and we get zero for y. so this means the x intercept is (0.0). then we plug zero in for y and get x=0 or -6. so the y intercepts are (0,0) and (-6,0)

Answer 2

ok how do u get min and max?

Answer 3

ok

Answer 4

can u help me with two more

Answer 5

yep go ahead man

Answer 6

f(x)=-(x+3)(x-5)

Answer 7

the minimum occurs at x = -3, the midpoint of your x=-6 and x=0. plugging that value of x=-3 into your expression x(x+6) you get -3*(-3+6) = -9. This is your minimum value of your function (vertex).

Answer 8

sorry, looks like dpalnc is better at this! i am in calc 3 and have not seen these in ages, but looks like i need to brush up myself! lol

Answer 9

ok
