You can find the x intercept by setting y to 0 and factor the equation.
0=2x^3+3x-2
0=(2x-1)(x+2)
We can make this equation =0 if x is -2 and 1/2.
So the x intercepts are (-2,0) and (0.5,0)
1 in 2. Each flip is independent of each other, so whether it is the 1st flip or 5th or 100th, the probability of getting tails on any one flip is 50%
9/10 is .9 as a decimal becsause anything after the decimal in the first place is like that
This is how graph gonna look like
Slop 2/1----->>>up 2 right 1
Y intercept ------1 beginning point
Y< so Shade below
