Find the value of Question: Find the value ofkso that the parabolay=x2+kx+100has only one x- intercept. Answer and Explanation: y = x^2 + kx + 100 Solutions for this quadratic equation are x1,2 = (-k +/- sqrt(k^2 - 4*1*100))/2*1 = (-...
To get its value, one way is to equate the function to zero then solve for the value of x. This will then give at least one value of x = a where the x-intercept is written as an ordered pair of the form (a, 0). There are also times when the function may have n...
