Answer:
f(x) = 2x + 1.
Step-by-step explanation:
In order to determine the function rule for the given table of values, we must start by finding the slope or the rate of change. Choose two ordered pairs from the table: (0, 1) and (1, 3).
Let (x₁, y₁) = (0, 1)
(x₂, y₂) = (1, 3)
Substitute these values into the following <u>slope formula</u>:
m = (y₂ - y₁)/(x₂ - x₁)
m = (3 - 1)/(1 - 0)
m = 2/1 = 2
Therefore, the <u>slope</u> of the function is, <em>m</em> = 2.
Next, we must determine the <u>y-intercept</u>, which is the point on the graph where it crosses the y-axis, with coordinates of (0, <u><em>b</em></u><em> </em>). From the given table of values, the y-intercept is (0, 1), for which its y-coordinate is the value of<em> b</em> = 1.
Therefore, the function rule that represents the given table of values is:
<h3>
f(x) = 2x + 1. </h3>
