Answer:
terms were improperly combined
Step-by-step explanation:
I find the easiest way to identify the error in a solution is to solve it myself and compare with what is shown as being done.
Here, we're starting with ...
If we identify the g-terms and the constant terms, we can group them the way Tyson did:
The next step is to combine like terms. We can factor out g, so the coefficients are easier to see and combine.
The error is 1 3/10 was combined with -2/10 as a constant instead of being combined with -4/5 as a coefficient of g.
Option B: 5 is the value of f(3)
Explanation:
The equation of the piecewise function is given by
We need to find the value of
The value of the function f can be determined when by identifying in which interval does the value of
lie in the piecewise function.
Thus, lies in the interval
, the function f is given by
Substituting in the function
, we get,
Thus, the value of is 5.
Therefore, Option B is the correct answer.
