Question

how do you sketch the graph of the equation 2x^2-3x

Answer 1

this factories to x(2x - 3)
when this = 0 , x=0 and 3/2
so u have the 2 intercepts on the x-axis

Answer 2

its a quadratic so the shape is a parabola and as the coefficient of x^2 is positive it will open upwards and have a minimum value

Answer 3

do u know any calculus?

Answer 4

no, I am currently in pre-calculus and we have been reviewing algebra two. We haven't gotten to actual calc yet

Answer 5

ok - i asked this because u can use calculus to find the minimum value of the function

Answer 6

Oh, okay. Yeah, we haven't gotten to any of that stuff yet

Answer 7

but the minimum value of x will be 0+ 3/2 / 2 = 0.75

Answer 8

yours a rough sketch
