Question

If f(2) = 22 – 5, then what is the value of f(2) + f(5)?

Answer 1

Answer:

67

Step-by-step explanation:

With the information of f(2) = 22-5,  you can assume the equation will be f(x) = 11x-5. Using this, you can calculate f(5) by doing 11(5)-5, which is 50. 22-5 is 17, so 50+17=67

Answer 2

22-5=f(2)

10.5-2.5=f(1)

52.5-10.5=f(5)

22-5+52.5-10.5

17+42=69

69
