A rational function that has an y-intercept of 7 is:
y = 7/(x + 1)
How to get the rational function?
A general rational function is:
y = a/(b + x).
And the y-intercept is the value that y takes when x = 0, in this case the y-intercept is 7, so we must have:
y = a/(b + 0) = 7
So, we just need to find two numbers a and b such that:
a/b = 7
For example, if we take b = 1, then:
a/1 = 7
a = 7
Then a rational function that has an y-intercept of 7 is:
y = 7/(x + 1)
