Math Problem Statement
Which statement is true regarding the graphed functions?
Solution
Looking at the graph, we have two functions: (in blue) and (in red). Let's analyze the given points from the graph to check which statement is true.
Step 1: Find the value of and
-
From the graph, at :
- (the blue curve is at 4 when )
- (the red curve crosses the x-axis at 0)
-
Now for :
- (the red curve reaches a value of 4 when )
Step 2: Check each option
-
Option 1: and
- Incorrect. , not 2.
-
Option 2: and
- Correct! This matches the values from the graph.
-
Option 3: and
- Incorrect. , not 0.
-
Option 4: and
- Incorrect. does not exist on the graph and is not 4.
Conclusion:
The correct statement is Option 2: and .
