Solution

It seems like you are comparing two functions f(x)f(x) and g(x)g(x) based on certain properties such as their slopes, values at specific points, and yy-intercepts. Without the explicit definitions or graphs of the functions f(x)f(x) and g(x)g(x), it’s challenging to determine the correct comparisons directly. However, I can provide a guide on how to analyze each option:

A. The slope of f(x)f(x) is less than the slope of g(x)g(x)

  • This comparison is about the rate of change of each function. If both f(x)f(x) and g(x)g(x) are linear functions (in the form y=mx+by = mx + b), the slope is the coefficient mm. Check if the slope of f(x)f(x) is less than the slope of g(x)g(x).

B. f(1)=g(1)f(1) = g(1)

  • This means that at x=1x = 1, both functions give the same output. To check this, you would evaluate both functions at x=1x = 1 and compare the results.

C. f(2)>g(2)f(2) > g(2)

  • Here, you would evaluate both functions at x=2x = 2 and check if f(2)f(2) is greater than g(2)g(2).

D. The yy-intercept of f(x)f(x) is equal to the yy-intercept of g(x)g(x)

  • The yy-intercept is the point where the function crosses the yy-axis, which happens when x=0x = 0. You would compare f(0)f(0) and g(0)g(0) to see if they are equal.

To determine which two statements are true, you would need the specific expressions or graphs for f(x)f(x) and g(x)g(x).

Do you have the functions or a graph for more context? Feel free to upload any images or details.


Here are five related questions:

  1. How do you determine the slope of a function from its equation?
  2. What does it mean for two functions to have the same yy-intercept?
  3. How can you find the value of a function at a specific point, such as f(1)f(1)?
  4. What does it mean for one function's value to be greater than another's at a given point?
  5. What are the key differences between a linear and a non-linear function in terms of slopes?

Tip: Always check for critical points like x=0x = 0, which gives the yy-intercept, and points like x=1x = 1 or x=2x = 2 for comparisons.
