Math Problem Statement
Solution
I see you've uploaded an image with questions about analyzing a linear function. The function in question is:
Let's go through the questions one by one:
a) State the integer coordinates of the y-intercept:
The y-intercept occurs when . To find the y-intercept, substitute into the equation:
Thus, the y-intercept is at .
b) State the integer coordinates of the x-intercept:
The x-intercept occurs when . Set and solve for :
Rearranging the equation:
Multiply both sides by :
Now, divide by 2:
Thus, the x-intercept is at .
c) State the interval for representing the mathematical domain:
Since this is a linear function (a straight line), the domain of is all real numbers. So, the domain is:
d) State the interval for representing the mathematical range:
For a linear function, the range is also all real numbers. So, the range is:
e) Is this function increasing or decreasing on its domain?
The slope of the line is , which is negative. This means the function is decreasing on its domain.
f) Fill in the end-behavior: as , ?
As , since the slope is negative, .
g) Fill in the end-behavior: as , ?
As , since the slope is negative, .
Let me know if you need further explanations or if you'd like to explore related questions! Here are 5 related questions you may find interesting:
- How do you determine the slope and y-intercept of a linear function from its equation?
- How would the graph of this linear function look if the slope were positive instead of negative?
- What would happen to the graph if the constant term in the equation (the y-intercept) changed?
- How can you identify the increasing or decreasing nature of a linear function by its slope?
- What is the significance of the domain and range in the context of real-world problems?
Tip: The slope of a linear function tells you the rate at which changes with respect to , while the y-intercept is where the graph crosses the y-axis.
