can you explain how a table can be used to find the rate of change

Vocaloid:

Rate of change between a and b = Is [f(b) - f(a)] / (b - a) So you would use the table to find the values of f at a and b, then plug everything into the formula and solve for rate of change

hannah228:

im still confused

Vocaloid:

so, let's say you are asked to find the rate of change of f(x) between x = 2 and x = 3 you would look at the table, find the value of the function at x = 2 and x = 3, then plug these values into the formula

Vocaloid:

so you would plug f(3) = 4 and f(2) = 3 into the rate of change formula to get the rate of change
