19. Consider the following function

NAKMATHAPT2 9.2.005.EP. MY NOTES ASK YOUR TEACHER Consider the following function. f ( x ) = xz - x - 20 x2 + 4x Find each value. (If an answer does not exist, enter DNE.) f(-4) = lim f(x ) = x - -4 Determine whether the function is continuous or discontinuous at x = -4. Examine the three conditions in the definition of continuit O The function is continuous at x = -4. O The function is discontinuous at x = -4
