Question

Find R(2) = f(20) + g(x) where f(x) = 22 - 16 and g(2) = 72 + 4.

a) 102
b) 84
c) 70
d) 88

Answer 1

After evaluating both functions, f(20) is 6 and g(2) is 76, so R(2) equals 82, which is not listed in the provided options.

Step-by-step explanation:

To solve for R(2), we need to first evaluate f(20) and g(2). The function f(x) = 22 - 16 is independent of x, so f(20) is simply 22 - 16, which equals 6. Next, we evaluate g(2) which is given as 72 + 4, and this equals 76. Now, we add the two results to find R(2).

R(2) = f(20) + g(2) = 6 + 76 = 82

Thus, the correct answer is not listed among the options provided. There seems to be an error in the question or the options given.
