Graph f(x)=-3

Problem

ƒ(x)=−3

Solution

1. Identify the type of function. The expression ƒ(x)=−3 is a constant function, which means the output value is always −3 regardless of the input x

2. Determine the geometric representation. In the Cartesian coordinate system, a constant function ƒ(x)=c represents a horizontal line.

3. Locate the y-intercept. Since the function is always −3 the line passes through the point (0,−3) on the y-axis.

4. Plot the line. Draw a straight horizontal line that extends infinitely to the left and right, passing through every point where the y-coordinate is −3 such as (−2,−3) (0,−3) and (2,−3)

Final Answer

ƒ(x)=−3
