Solution
Question 1: a) The standard function here is y = |x|. The graph of y = |x| is a V shape with the point at the origin (0,0). The function y = 2|x + 2| - 1 is a transformation of the standard function. It shifts the graph 2 units to the left and 1 unit down. The 2 in front of the absolute value stretches the graph vertically by a factor of 2.
b) The standard function here is y = โx. The graph of y = โx is a half parabola lying on its side. The function y = โ(x - 13) + 1 is a transformation of the standard function. It shifts the graph 13 units to the right and 1 unit up.
Question 2: a) The function y = x - sinx is not symmetric about the y-axis or the origin. You can test this by replacing x with -x and seeing if the equation remains the same (symmetry about the y-axis) or changes sign (symmetry about the origin). Neither happens in this case.
b) The function y = x^4 - x^2 - 3 is symmetric about the y-axis. Replacing x with -x gives the same equation.
Question 3: a) The limit as x approaches 4 of (4x - x^2) / (2 - โx) can be found by direct substitution, giving (16 - 16) / (2 - 2) = 0/0, which is an indeterminate form. You would need to use L'Hopital's rule or some algebraic manipulation to find the limit.
b) The limit as x approaches 0 of tan(3x) / sin(8x) can be found using L'Hopital's rule or by noting that as x approaches 0, both tan(3x) and sin(8x) approach 0, so the limit is 0/0, another indeterminate form.
c) The limit as x approaches infinity of (9x^4 + x^3) / (x^4 - 5x^2 + x - 2) can be found by dividing every term by x^4, the highest power of x in the denominator, and then taking the limit as x approaches infinity, giving 9 + 0 / 1 - 0 + 0 - 0 = 9.
Question 4: The horizontal asymptotes of the function f(x) = (x + 1) / (x^2 - 1) can be found by looking at the degrees of the numerator and denominator. Since the degree of the denominator is higher, the horizontal asymptote is y = 0. As x approaches infinity, the function approaches 0 from above, and as x approaches negative infinity, the function approaches 0 from below.
