Examples with solutions for Representations of Functions: Matching a table to a function

Exercise #1

Which of the following equations corresponds to the function represented in the table?

XY-3-1135246810

Video Solution

Step-by-Step Solution

We will begin by using the formula for finding slope:

m=y2−y1x2−x1 m=\frac{y_2-y_1}{x_2-x_1}

First let's take the points:

(−1,4),(3,8) (-1,4),(3,8)

m=8−43−(−1)= m=\frac{8-4}{3-(-1)}=

8−43+1= \frac{8-4}{3+1}=

44=1 \frac{4}{4}=1

Next we'll substitute the point and slope into the line equation:

y=mx+b y=mx+b

8=1×3+b 8=1\times3+b

8=3+b 8=3+b

Lastly we'll combine like terms:

8−3=b 8-3=b

5=b 5=b

Therefore, the equation will be:

y=x+5 y=x+5

Answer

y=x+5 y=x+5
