Question

the graph shows the weight of a bag of rice, y, as a function of the number of cups of rice used, x. how can you find the change in the x - values from 0 to 3? rate of change = \frac{change in y - values}{change in x - values}=\frac{15 - 21}{? 3 - 0 3×0 0÷3}

Explanation:

Step1: Recall change - formula

The change in a variable from $a$ to $b$ is found by $b - a$. Here, we want to find the change in $x$ - values from $x_1=0$ to $x_2 = 3$.

Step2: Calculate change

Using the formula $x_2 - x_1$, we substitute $x_1 = 0$ and $x_2=3$ to get $3-0$.

Answer:

$3 - 0$
