Mathematics B Assignments: Functions Task 1. (KPS, MPS) i) With K=0, determine the function and sketch it on a suitable domain. Point A: (1, 4) Point B: (2, 2) Point C: (4, k) or (4, 0) Using the equation y = ax² + bx + c substitute the 3 points (x and y) into three equations to find the function. Point A: 1…………… 4 = 1x + 1x + 1c Point B: 2…………….2 = 4x + 2x + 1c Point C: 3…………….0 = 16x + 4x + 1c Using the simultaneous equation function on the graphics calculator, find the function

Geometry different from Algebra? answer: Geometry is different from Algebra because geometry has shapes, measurement, line segments, and graphing. While Algebra has general statements of realizations utilizing letter and other variables. Algebra doesn't use as many shapes as Geometry. While Geometry doesn't have as many unknown values. Also Geometry uses plane and 3 dimensional shapes. Algebra has more mathematics and unknown values. 3. How is Geometry similar to Algebra?

Exercise 4.1, problem 5a for i := 1 to 123 do for j := 1 to i do print i * j a) How many times is the print statement of the third line executed? Since we have to count iterations starting from one until 123, the first count would be 1 then 3 then 6 and so forth. The segment can be translated to (n)(n+1)/2 where 123 would be (n). (123)(123 + 1)/2 The statement is executed 7626 times. Exercise 4.2, problem 18a a) How many permutations of 1, 2, 3 have k ascents, for k = 0, 1, 2? Ascent

Explain the five steps for solving rational equations. Can any of these steps be eliminated? Can the order of these steps be changed? Would you add any steps to make rational equations easier to complete or understand? - Find the LCD of the terms in the equation. - Multiply each side of the equation by the LCD. - Simplify each term. - Solve the resulting equation. - Check each answer in the given equation. Any value that makes a denominator equal 0 should be rejected because it is an extraneous
