Which is a quadratic function?
f(x) = 2x + x + 3
f(x) = 0.x2 - 4x + 7
f(x) = 5x2 - 4x +5
f(x) = 3x3 + 2x + 2

step-by-step explanation:

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2

dont trust me im no expert these losers made me fail a test bro this sucks

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
