Answer :
Final answer:
To find the equivalent expressions to f(4 + 5), substitute 4 + 5 into the function f. The equivalent expressions are 44 + 5, which simplifies to 49.
Explanation:
To find the equivalent expressions to f(4 + 5), we can substitute the expression 4 + 5 into the function f. This gives us:
f(4 + 5) = f(9)
Therefore, the equivalent expressions are:
- a. 2: This expression is not equivalent to f(4 + 5).
- b. 20f: This expression is not equivalent to f(4 + 5) as it includes the variable f.
- c. 44 + 5: This expression is equivalent to f(4 + 5) as it simplifies to 49.
- d. 97 + 4f + 5f: This expression is not equivalent to f(4 + 5) as it includes the variables f.
