Answer:
To evaluate the function when x=4, we need to substitute the value of x into the given function and simplify the expression. Let's assume the function is denoted as f(x).
Given that f(x) = 2x - 5, we can substitute x=4 into the function:
f(4) = 2(4) - 5
= 8 - 5
= 3
Therefore, when x=4, the value of f(x) is equal to 3.
In summary:
- Blue: f(4) = 3
- Teal: f(4) = 3
- Yellow: f(4) = 3
- Red: f(4) = -1 (This seems to be a mistake in the calculation. The correct value should be 3, not -1.)
