math help problem 2

Question

Let f(x)=5x+8/8x^2+2x−15=(5x+8)/(2x+3)(4x−5)

ect  

2) The y intercept is at the point:   



3) The x intercept(s) is/are at the point(s): 

Answer 1

for f(x) = (5x+8)/(2x+3)(4x-5)

use a graphing calculator

and see where the curve intersect the axes

or set x =0 and solve for y

= 8/3(-5)= -8/15 =-.533

(0,-.533) is the y intercept

set y=0 and solve for x.

5x+8 = 0

x =-8/5=-1.6

(-1.6,0) is the x intercept
