Sep 2, 2010 · Hi juventinoalex, How did you calculate f (0) ? To find f (2), look at your graph and see what the value of y is on the curve when the value of x is 2. y = f (2) (2, f (2)) If you want to define the …

Jun 25, 2016 · The point is to shift the graph up or down so that the graph crosses y= 0 between every max-min pair. For example, the function y= f (x)= 2x^3- 18x+ 12x- 3 has a local maximum value, at …

Feb 9, 2013 · The area A of the region S that lies under the graph of the continuous function is the limit of the sum of the areas of approximating rectangles: (a) Use this definition to find an expression for …

Oct 6, 2008 · On my TI-84 Plus graphics calc, I've found there's a function called nDeriv, that can be used to find a derivative. It sounds useful, so how do I use it?

Mar 9, 2013 · Graph the following function over a two-period interval. Label every tick mark on the x-axis (pick appropriate value to make your graph fit) y = -2sin(1/4x)

Aug 31, 2009 · Obvious first step- graph the function you are given. The put a ruler along it to draw the tangent line "by eye". Find two points on it and calculate the slope as above. When I was in high …

Sep 21, 2012 · The point (2,3) is one the graph of y=f(x). Determine the corresponding coordinates of this point on the graph of y = -2(f(2(x+5))-4. Not sure how to do this - if anyone could help I would …

Mar 23, 2010 · During a 9 hour snowstorm, it snows at a rate of 1 inch per hour for the first 2 hours, at 2 inches per hour for the next 6 hours, and at a rate of 0.5 per hour for the final hour. Write and graph …

Dec 5, 2009 · A periodic function is one whose values are repeated at regular intervals or periods. On the graph of the function, the period itself is the horizontal distance between two consecutive …

Oct 7, 2008 · When I think about the inverse graphically, it's not the graph of a function at all. Look at the attached image |x| in red, and it's inverse in blue (reflection in y=x) which is undefined for x<0 since it …
