QUESTION 1 Is The Function x+2x-4 Increasing or Decreasing at the Point (-1, -7)? Explain Why? O a. Increasing at all values of x especially at x = -1 since its first derivative y 3x2 +2 changes signs from positive to negative near x = -1 Ob. Increasing at all values of x especially at x -1 since its first derivative y = 3x +2 changes signs from negative to positive near x -1 Oc. Increasing at all values of x especially at x -1 since its first derivative y = 3x +2 is strictly positive for all values of x in the whole set of real numbers Od. Decreasing at all values of x especially at x -1 since its first derivative y =3x2 +2 is strictly negative for all values of x in the whole set of real numbers Oe. None of the Above QUESTION 2 Write the equation of the tangent to the parabola y = 4x that makes an angle of 45° with the x axis Oa.y x+1 Ob.y=x-5 Ocy x+5 Od.y x+7 Oe.y x-1
