Answer:
Depends on which function is which...
Step-by-step explanation:
The blue graph is the same as the yellow graph but raised up 1 unit. That means either:
blue function rule = yellow function rule + 1
or
yellow function rule = blue function rule - 1
Your picture doesn't say which function is <em>f</em> and which is <em>g</em>.
If, just to pick a possibility, the blue function is <em>g</em>(<em>x</em>), then
g(x) = f(x) + 1
If the blue function is <em>f</em>(<em>x</em>), then
g(x) = f(x) - 1
You have to combine like terms, so 3b plus 2b equals 5b and you can't add b to 5a because they aren't defined, therefore th answer is 5a+b.
