Given the curve y= 2x^2 - 4x
+8
We need to find the x and y
intercepts.
First we will determine the
y-intercepts.
The y-intercept is when the curve meets the
y-axis, then the value of x is 0.
==> y= 0+ 8 =
8
Then the y-intercept is (0,
8).
Now we will determine the
x-intercept.
Then y=
0.
==> 2x^2 -4x +8 =
0
==> (2x+4)(x-4) =
0
==> x= -2
==>
x= 4
Then we have two x-intercepts ( -2, 0) and (4,
0)
Then the intercepts
are:
y-intercept (0, 8)
x-intercepts (-2, 0) and
(4,0)
