Question #e04fc

Answer 1

`"see explanation"`

Explanation:

`"to find the intercepts of "f(x)`

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

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

`x=0toy=(-1)(-4)=4larrcolor(red)"y-intercept"`

`y=0to(x-1)(x-4)=0`

`"equate each factor to zero and solve for x"`

`x-1=0rArrx=1`

`x-4=0rArrx=4`

`rArrx=1,x=4larrcolor(red)"x-intercepts"`
