WebOct 15, 2024 · For example, the rational function R (x) = ( (x+1) (x-1))/ (x-1) has a common factor of x-1 in the numerator and denominator. x-1 =0 when x=1, so we have a hole at x=1. If we were to cancel the... WebFeb 23, 2024 · Sketch the graph of the rational function f(x) = x + 2 x − 3 Solution First, note that both numerator and denominator are already factored. The function has one restriction, x = 3. Next, note that x = −2 makes the numerator of equation (9) zero and is not a restriction. Hence, x = −2 is a zero of the function. cystic fibrosis protein defect

Find the x - and y -intercepts of the graph of y = r(x), if they exist. Determine the location of any vertical asymptotes or holes in the graph, if they exist. WebFeb 23, 2024 · Step 3: The numerator of equation (12) is zero at x = 2 and this value is not a restriction. Thus, 2 is a zero of f and (2, 0) is an x-intercept of the graph of f, as shown in Figure 3.17.3.12. Step 4: Note that the rational function is already reduced to lowest terms (if it weren’t, we’d reduce at this point). cystic fibrosis of pancreas
