Step-by-step explanation:
The meaning of f(2) is x = 2. The question is asking us to find the y-value when x = 2.
According to the graph, when x = 2, y is somewhere between 8 and 10. The graph looks like it intersects right in the middle of those 2, so the y-value when x = 2 would be 9.
Therefore, f(2) = 9.
Answer:
169
Step-by-step explanation:
Add: 9 + 4 = 13
Exponentiation: the result of step No. 1 ^ 2 = 13 ^ 2 = 169
Divide: 15 / 3 = 5
Subtract: 5 - the result of step No. 3 = 5 - 5 = 0
Add: the result of step No. 2 + the result of step No. 4 = 169 + 0 = 169
