What is the horizontal asymptote of the function f(x)=2x−5?

There is no asymptote

Step-by-step explanation:

y=2x−5 = (2x¹ - 5) / x⁰

y=2x-5 is an oblique line, the degree of numerator > degree of denominator

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.

the correct answer would be c
