Find {eq}f {/eq} if {eq}f'(x) = \dfrac{4x^2+7}{1+x^2} {/eq} and {eq}f(0) = -1 {/eq}.


Find {eq}f {/eq} if {eq}f'(x) = \dfrac{4x^2+7}{1+x^2} {/eq} and {eq}f(0) = -1 {/eq}.

Indefinite Integral:

One of the uses of indefinite integrals is in obtaining general and specific antiderivatives.

For specific antiderivatives, we need initial values.

The indefinite integral that we'll use is:

{eq}\displaystyle \int\frac{\mathrm{d}x}{1+x^2}=\tan^{-1}(x) + C {/eq}

Let's get {eq}f(x) {/eq} utilizing {eq}f(x) = \displaystyle \int \dfrac{4x^2+7}{1+x^2} \, \mathrm{d}x {/eq}.

To be able to use {eq}\displaystyle...
