The slop of the tangent line g(x) = 1 - x^2 at x= -1
The slop of the tangent line g(x) = 1 - x^2 at x= -1

1 Answer

  • 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
