Answer:

Step-by-step explanation:

When the graph crosses the x axis value of the graph is zero

Therefore 6x2-11x-10=0

6x2-15x+4x-10=0

3x(2x-5)+2(2x-5)=0

(3x+2)(2x-5)=0

So, it shows that 3x+2=0 and 2x-5=0

x=[tex]-\frac{2}{3}[/tex] and x=2.5

x intercepts are ([tex]-\frac{2}{3}[/tex],0) and (2.5,0)

When x=0

y=6x2-11x-10 = 0 - 0 -10 = -10

y intercepts in (0, -10)
