Find the turning point(s) of the following function f(x) = x^2-2x+4. Determine whether the turning point is a minimum or maximum.

Differentiate f(x) with respect to x.You get f'(x) = 2x - 2Turning points occur when the derivative of f(x) = 0. In other words, when f'(x) = 0. This occurs when x=1.Now to determine if maximum or minimum...

Find the equation of the straight line perpendicular to 3x+5y+6=0 that passes through (3,4)

First we need to write the equation in the form y = mx + c 3x + 6= 5y (3x+6) / 5 = y -3/5x + 6/5 = ynow we know that the gradient is -3/5 therefore the perpendicular gradient is 5/3.so our line equation i...
