What is the rate of change for the interval between 0 and 2 for the quadratic equation as f(x) = 2x2 + x – 3 represented in the table? (The table has this: Left side X and the options going down are -2, -1, 0, 1, 2. Right Side f(x) and the options going down are 3, -2, -3, 0, 7) THE ANSWER OPTIONS ARE: 1/5, 4, 5, 10
By definition the rate of change of a function is given by:
\(AVR = \frac{f(x2) - f(x1)}{x2 - x1}\)
For the interval [0, 2] We have to make use of the table:
\(f(0)=-3
f(2)=7\)
Therefore, substituting values in the given expression we have that the average change of rate is given by:
\(AVR = \frac{7-(-3)}{2-0}\)
Rewriting we have:
\(AVR = \frac{7+3}{2-0}\)
\(AVR = \frac{10}{2}\)
\(AVR = 5\)
Answer:
the rate of change for the interval between 0 and 2 is:
\(AVR = 5\)
