For example: if you are asked to find out the square of 5, 5, you'll simply need to multiply 5 by itself: 5 = 5 x 5 = 25. If you have two points, (x 1, y 1) and (x 2, y 2 ), you can define the exponential function that passes through these points by substituting them in the equation y = ab x and solving for a and b. Calculus: Fundamental Theorem of Calculus Press ENTER or = to solve the equation. What can we conclude about the polynomial represented by the graph shown in Figure $\PageIndex{15}$ based on its intercepts and turning points? Learning a new skill can be daunting, but breaking the process down into small, manageable steps can make it much less overwhelming. Only thing that I would improve is maybe giving more answer options and sometimes making them a bit cleaner to see whether the minus is on the denominator or numerator. Because even if u are a shark in maths u one day u will find difficulty in something.
