The problem asks us to fill in two equations derived from the information g(x) = a x^3 + b x^2 + 16 with a turning point and an x-intercept at x = 2. To analyze this, consider the function and its derivative. First, compute the derivative: g'(x) = 3a x^2 + 2b x. Since x = 2 is a turning point, the derivative must be zero at x = 2. Plugging in x = 2 gives 3a(2^2) + 2b(2) = 0, which simplifies to 12a + 4b = 0. Dividing by 4 yields the equation 3a + b = 0. Second, use the inf......Login to view full explanation
