-8,y intercept is when x = 0,x- intercepts: 2, -8,......
For the function, y = (x - 2) (x + 8) (5x - 3)
its y-intercept is, y=_______________
its x-intercepts are, x+_________________


If you could explain how you get the answers that would be great!

-
y intercept when x = 0 ==> (-2)* (8)* (-3) = 6 * 8 = 48
x intercepts: when y = 0 ==> x = -8, 3/5 and 2 (look at what makes the inside of each brackets equal 0)

Ok easy:) think bout the alphabet xyz x comes first and y comes second so example (x-5) so thats bascally saying (1x-5y) so so x= 1x and y = 5y so the x for your problem eould equal 7x :) you do y :) hood luck lol if u get stuck just go to google :)

y = (x - 2) (x + 8) (5x - 3)

x intercepts are when y = 0,
0 = (x - 2) (x + 8) (5x - 3)
x = 2, -8, 3/5

y intercept is when x = 0,
y = (0 - 2) (0 + 8) (5(0) - 3) = (-2)(8)(-3) = 48

x- intercepts: 2, -8, 3/5
