Chapter 2: Q. 63 (page 210)

In Exercises 63–68, find a function that has the given derivative and value. In each case you can find the answer with an educated guess-and-check process while thinking about the
chain rule.
$f' (x) = 5 {(x^{2} + 1)}^{4} (2 x), f (0) = 1$

Short Answer

Expert verified

The function is $f (x) = {(x^{2} + 1)}^{5}$

Step by step solution

Step 1. Given Information

The given derivative is $f' (x) = 5 {(x^{2} + 1)}^{4} (2 x), f (0) = 1$

localid="1649330017496" $\frac{d}{d x} f (x) = 5 {(x^{2} + 1)}^{4} (2 x) d f (x) = 5 {(x^{2} + 1)}^{4} (2 x) d x$

Step 2. Finding antiderivative

$f (x) = \int 5 {(x^{2} + 1)}^{4} (2 x) d x f (x) = \int 5 t^{4} (2 x) \frac{d t}{2 x} = 5 \int t^{4} d t f (x) = 5 \frac{t^{5}}{5} + C f (x) = t^{5} + C f (x) = {(x^{2} + 1)}^{5} + C$

Step 3. Finding the value of C

Given that $f (0) = 1$

${(0 + 1)}^{5} + C = 1 1 + C = 1 C = 0$

The function become

$f (x) = {(x^{2} + 1)}^{5} + 0 f (x) = {(x^{2} + 1)}^{5}$
