Question

What are the x– and y–intercepts of y = 2x^2 – 10x + 8?
Answer
A. x–intercepts: (1, 0) and (4, 0)
y–intercept: (0, 8)
B. x–intercepts: (1, 0) and (4, 0)
y–intercept: (0, 4)
C. x–intercepts: (–1, 0) and (–4, 0)
y–intercept: (0, 8)
D. x–intercepts: (–1, 0) and (–4, 0)
y–intercept: (0, 4)

Answer 1

y intercept mean x =0
y(0) = 8
(0,8)

x intercept :
0 = 2x^2 -10x + 8
2x^2 -8x-2x+8
2x(x-4)-2(x-4)
(2x-2)(x-4)
x = 1 , x = 4

(1,0) , (4,0)

A
