20. (02.05 LC) The graphs of functions f(x) and g(x) = f(x) + k are shown: (x f(x) 6 5 g(x) 3 2 1 a 2 What is the value of k? O k = 2 O k = -2 O k = 1 O k = -1 (1 point)

no oblique asymptote

step-by-step explanation:

to find the oblique asymptote of f(x)

here numerator has degree 1 and denomintor degree 2

degree of numerator < degree of denominator

hence there is no oblique asymptote

when the degree of the denominator > that of the numerator, we saw that the value in the denominator got so much bigger, so quickly,   giving us a horizontal asymptote of the x-axis. or we can write

f(x) = a polynomial of x + a proper fraction.

in this case only we have oblique asymptotes but not when numerator has less degree.
