Question

Remember that a function can be represented with a graph, a table of numbers, and algebraic formula, or words. for each of the following, find f(1)
(1) 100 POINTS FOR FIRST ANSWER

Answer 1

In this question, we have a graph given. And using that graph we have to find the value of f(1) .

f(1) means the y value when x=1 .

So we need to check the value of y at x=1 .

And if we follow the graph, we will see that at x=1, y=2.5 . So the value of f(1)=2.5 and that's the required answer .
