Given:
f(x) =20/1 + 9^3x
Determine the y-intercept.
Solution:
In order to determine the y-intercept, we only need to equate f(x) or change it by y, since the y-intercept of a line or a function is often written in slope-intercept form.
y = mx + b
f(x) = 20/1 + 9^3x
y = 20/1 + 9^3x
y = 20 + 9^3x
Final answer:
y = 20 + 9^3x
