What are the x– and y–intercepts of the quadratic equation y = 2x2 – 8x + 6?

Question

anonymous · Answer

For the y-intercept, plug in 0 for x.
For the x-intercepts, plug in zero for y and factor it.

amorfide · Answer

factorise to get x

factorising gives
2x2 -6x-2x+6
2x(x-3)-2(x-3)

(2x-2)(x-3)
x=2/3
or 
x=3

sub both into the original equation to get 2 y values
this gives two coordinates

anonymous · Answer

0 = 2(x^2 - 4x + 3)
0 = (x - 3)(x - 1)
x = 3 and 1.

amorfide · Answer

yeah you are right
i got 2/2 not 2/3 lol

anonymous · Answer

Therefore, the y-intercept is 6. (0, 6)
The x-intercepts are 3 and 1. (3, 0) (1, 0)

anonymous · Answer

for the answer choices there is no y-intercept that =-6

anonymous · Answer

I changes it

i see now lol.

can you help me on another one?

anonymous · Answer

Sure

anonymous · Answer

Describe the differences between the graph of y= -3/4(x-6)^2+4 and the standard position graph of y = x^2.
