Final answer:
To rewrite the given explicit formulas in function form, isolate the variable 'n' on one side of the equation. For f(n) = 19 - 7(n-1), the function form is f(n) = 26 - 7n. For g(n) = 5 + 4(n-1), the function form is g(n) = 1 + 4n.
Step-by-step explanation:
To rewrite the given explicit formulas in function form, we need to isolate the variable 'n' on one side of the equation.
For the formula f(n) = 19 - 7(n-1), we can distribute the -7 and simplify to get f(n) = 19 - 7n + 7. Combining like terms, we have f(n) = 26 - 7n.
Similarly, for the formula g(n) = 5 + 4(n-1), we can distribute the 4 and simplify to get g(n) = 5 + 4n - 4. Combining like terms, we have g(n) = 1 + 4n.
