Question

f(x)=2x-5 en el intervalo [2,3]​

Answer 1

1). f(x1). 2) f(x2)

f(2). 2) f(3)

1) f(x)=2x-5. 2). f(x)=2x-5

=2(2)-5. =2(3)-5

=4-5. =6-5

= -1. = 1

$tvm = \frac{f(x2) - f(x1)}{x2 - x1} \\ tvm = \frac{1 - ( - 1)}{1 - ( - 1)} \\ tvm = \: \frac{1 + 1}{1 + 1} \\ tvm = \: \frac{2}{2} \\ tvm = 1$
