To find the range of a continuous linear function when the values of x are between a and b (inclusive), follow these simple steps:
- Identify the function: Look at the linear function, which usually looks like f(x) = mx + c, where m is the slope and c is the y-intercept.
- Calculate the endpoints: Plug the values of a and b into the function to find the corresponding f(a) and f(b).
- Determine the range: The range will be from the smaller of f(a) or f(b) to the larger of the two results.
So, you’re looking for the lowest and highest y-values that the function takes when x is between a and b!
