Question

What are the intercepts for `y=x^2-5x+4`?

Answer 1

`y=4" and " x=1,x=4`

Explanation:

`"to obtain the intercepts"`

`• " let x = 0, in the equation for y-intercept"`

`• " let y = 0, in the equation for x-intercepts"`

`x=0toy=4larrcolor(red)" y-intercept"`

`y=0tox^2-5x+4=0`

`rArr(x-1)(x-4)=0`
