Equation for the horizontal asymptote.

In summary, the equation for the horizontal asymptote is y = c, where c is a constant value. To find this equation, you need to determine the degree of the highest power of x in the polynomial and divide the coefficient of the highest power of x by the coefficient of the highest power of x in the denominator. The equation for the horizontal asymptote can have a fraction, and it is not the same as the x-axis. This equation is important because it helps us understand the behavior of a function and make predictions about its values at certain points.

How would you find the equation for the horizontal asymptote of the following exponential function?:
\(\displaystyle g(x) = -2f(2x - 6)\)

Let \(\displaystyle f(x) = 4^x\)

I would begin by looking at the horizontal asymptote of $f$...can you see what this is?
 

FAQ: Equation for the horizontal asymptote.

What is the equation for the horizontal asymptote?

The equation for the horizontal asymptote is y = c, where c is a constant value. This means that as the x-values increase or decrease without bound, the y-values will approach the constant value c.

How do you find the equation for the horizontal asymptote?

To find the equation for the horizontal asymptote, you need to first determine the degree of the highest power of x in the polynomial. Then, divide the coefficient of the highest power of x by the coefficient of the highest power of x in the denominator. The resulting value will be the constant c in the equation y = c.

Can the equation for the horizontal asymptote have a fraction?

Yes, the equation for the horizontal asymptote can have a fraction. This occurs when the degree of the polynomial in the numerator is greater than the degree of the polynomial in the denominator. In this case, the fraction will become the constant c in the equation y = c.

Is the horizontal asymptote the same as the x-axis?

No, the horizontal asymptote is not the same as the x-axis. The x-axis is a specific line with a y-value of 0, while the horizontal asymptote is a line that the graph of the function approaches as the x-values increase or decrease without bound.

Why is the equation for the horizontal asymptote important?

The equation for the horizontal asymptote is important because it helps us understand the behavior of a function as the x-values become very large or very small. It can also help us determine the end behavior of a graph and make predictions about the function's values at certain points.
