Solution

x-intercept is when y = 0

y = 3x^2 - 20x - 32 = 0

solving the qudratic equation:

x = [20 +/- sqrt (400 + 4*3*32)]/(2*3)

x = [20 +/- 28]/6

x = [8, -1.33]

2.

when f(x) = 0

-18x^2 + 17x + 10 = 0

Solving the qudratic equation:

x = [-17 +/- sqrt (289 + 4*18*10)]/(2*(-18))

x = -[-17 +/- sqrt 1009]/36

x = [(17 - sqrt 1009)/36, (17 + sqrt 1009)/36]

x = [-0.41, 1.35]

Let me know if you have any doubt.
