4

Step-by-step explanation:

8 x^4 - 3x -7

Let x = -1

8 (-1)^4 - 3(-1) -7

We know that (-1)^4 = (-1) *(-1)*(-1)*(-1) = 1

8 * 1 +3 -7

8+3-7

11-7

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.
