Question

Given the table of values what is the value of f(-34.2)?

X
23
-125.6
145.6
-34.2

Y
-34.2
134
-154
80.3

Answer 1

`80.3`

1) In this problem, we need to resort entirely to the table, since we don't know the rule of that function.

2) And since the question is what is f(-34.2) let's look for that in the column of x, to find the corresponding value when we plug -34.2 into the x-variable of that function.

3) So, we can tell that the answer is:

`f(-34.2)=80.3`
