find the stationary point of the curve for the equation y=x^2 + 3x + 4

dy/dx = 2x +32x + 3 = 0x= 3/2(3/2) 2 + 3(3/2) + 4 = 2.25 + 4.5 + 4 = 10.75

A straight line passes through the point (0, 6) and is perpendicular to y = 4x - 5. Find the equation of this line, giving your answer in the form y = mx + c .

perpendicular so the gradient is -1/4 y= -1/4x +CSub in the coordinate (0,6) 6 = -1/4 (0) +C C=6y=-1/4x +6
