Answer:
f(5) = 31/11
f'(5) = 4/11
Explanation:
y = 4/11x + 1
f(x) = 4x/11 + 1 ==> y = f(x)
f(5) = 4(5)/11 + 1 ==> substitute 5 for x
f(5) = 20/11 + 1 ==> simplify
f(5) = 20/11 + 11/11 ==> make common denominators to simplify easier
f(5) = (20+11)/11
f(5) = 31/11
f'(x) = 4/11
Hence, f'(5) = 4/11 since every value of x will make the derivative 4/11.
