Functions and Y Intercept and X Intercept Calculator

Calculator Instructions:

Enter function
  Search Engine Shortcut Examples:

y=5
f(x)=3^x
  
<-- Enter Terms
    Note: Go premium for additional features

With the function that you entered of f(x)=3x, plot points, determine the intercepts, domain, range

Determine function type:
Since we have a number raised to a variable, this is an exponential function

Now Plot points from 10 to -10

Determine the y-intercept:
The y-intercept is found when x is set to 0. From the grid above, our y-intercept is 1

Determine the x-intercept
The x-intercept is found when y is set to 0
Determine the domain of the function:
The domain represents all values of x that you can enter
The domain is (-∞, ∞) or All Real Number

Determine the range of the function:
The range is all the possible values of y or f(x) that can exist
The range is (0, ∞) or All Positive Real Numbers
