Math Problem Statement
f(x)=5x-3
Solution
You provided the function .
This is a linear function with a slope of 5 and a y-intercept of -3. To analyze this function:
- Slope: The slope of the line is 5, meaning that for every unit increase in , increases by 5 units.
- Y-intercept: The y-intercept occurs where . Substituting into the equation, we get , so the y-intercept is .
- Graph: The function is a straight line with an upward slope, passing through the point .
- Domain: The domain of the function is all real numbers, , since there are no restrictions on .
- Range: The range is also all real numbers, , as the line extends indefinitely in both directions.
Would you like to solve for specific values of , or any other details?
