WebThen, f is O(x5). c. f(x) = (x4 + x2 + 1)=(x4 + 1). Divide the denominator into the numerator in order to write the function as f(x) = 1 + x2 x4 + 1: Since the fraction is O(1), therefore f(x) is O(1). d. f(x) = (x3 + 5logx)=(x4 + 1). The denomi-nator is bigger than the numerator! Since x4 dom-inates 1, and x3 dominates logx, we can disregard Webf (x) = f (−x) for all x In other words there is symmetry about the y-axis (like a reflection): This is the curve f (x) = x 2 +1 They got called "even" functions because the functions x 2, x 4, x 6, x 8, etc behave like that, but there are other functions that behave like that too, such as cos (x): Cosine function: f (x) = cos (x)

WebMay 28, 2016 · • If f(x) = f( -x) , then f(x) is even Even functions have symmetry about the y-axis. • If f( -x) = - f(x) , then f(x) is odd Odd functions have symmetry about the origin. Test … WebSep 18, 2024 · On the graph of a line, the slope is a constant. The tangent line is just the line itself. So f' would just be a horizontal line. For instance, if f(x) = 5x + 1, then the slope is just 5 everywhere, so f'(x) = 5. Then f''(x) is the slope of a horizontal line--which is 0. So … popovich pet theater tour
