given the provided quadratic function g%28x%29=2x%5E2%2B7x%2B2
A. find the value of the discriminant
Delta = 7^2-4*2*2=49-16=33
B. Use the descriminant to determine the number and type of solutions
Delta > 0 => 2 Real solution
C. find the x-intercepts
intercepts at x1=(-7+sqrt(33))/4, x2=(-7-sqrt(33))/4
D- find the y-intercepts
at x=0 y=2
