With the function that you entered of f, plot points, determine the intercepts, domain, range

Since you did not specify a qualifying variable or function notation in your expression, we will assume y
y = f

Determine function type:
Since we have a variable with no exponents, this is a linear function

Since this is a linear function, it is a direct variation equation: the constant of proportionality is

Now Plot points from 10 to -10
fPlug in xƒ(f) = fOrdered Pair

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

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

Determine the domain of the function:
The domain represents all values of f that you can enter
The domain is (-∞, ∞) or All Real Numbers

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