Q. Given the function g(x)=−x2−6x+14, determine the average rate of change of the function over the interval −5≤x≤2.Answer:
Define Function: We have the function g(x)=−x2−6x+14. To find the average rate of change over the interval [−5,2], we will use the formula for the average rate of change, which is (g(b)−g(a))/(b−a), where a and b are the endpoints of the interval.
Find g(−5): First, we need to find the value of g(−5). We substitute x=−5 into the function g(x). g(−5)=−(−5)2−6(−5)+14 g(−5)=−(25)+30+14 g(−5)=−25+30+14 g(−5)=5+14 g(−5)=19
Find g(2): Next, we need to find the value of g(2). We substitute x=2 into the function g(x). g(2)=−(2)2−6(2)+14 g(2)=−4−12+14 g(2)=−16+14 g(2)=−2
Calculate Average Rate of Change: Now we have the values g(−5)=19 and g(2)=−2. We can calculate the average rate of change using the formula (g(b)−g(a))/(b−a) with a=−5 and b=2.Average rate of change = (g(2)−g(−5))/(2−(−5))Average rate of change = (−2−19)/(2−(−5))Average rate of change = (−21)/(7)Average rate of change = −3
