Solve the function
Answer to Problem 38PFA
Option A
Explanation of Solution
Given information:
Calculation:
To recognize if a function is linear, quadratic (a parabola), or exponential without an equation or graph, look at the differences of the y-values between successive integral x-values.
If the difference is constant, the graph is linear.
If the difference is not constant but the second set of differences are constant, the graph is quadratic.
Option A
As in the table, the difference is constant, the graph is linear. So, it is linear function.
