Final answer:
To find f(7), use the Remainder Theorem after dividing f(x) by (x-7) and getting a remainder of 5.
Step-by-step explanation:
To find the value of f(7), we need to use the Remainder Theorem. The Remainder Theorem states that if a polynomial f(x) is divided by (x - a) and the remainder is c, then f(a) equals c.
In this case, the polynomial f(x) is divided by (x - 7) and the remainder is 5. So, f(7) equals 5.
