The slope f′(x) at each point (x,y) on a curve y=f(x) is given, along with a point (a,b) on the curve. Use this information to f

Montano1993 [528]

$f'(x)=\dfrac{4x}{1+7x^2}$

Integrating gives

$f(x)=\displaystyle\int\frac{4x}{1+7x^2}\,\mathrm dx$

To compute the integral, substitute $u=1+7x^2$ , so that $\frac27\,\mathrm du=4x\,\mathrm dx$ . Then

$f(x)=\displaystyle\frac27\int\frac{\mathrm du}u=\frac27\ln|u|+C$

Since $u=1+7x^2>0$ for all $x$ , we can drop the absolute value, so we end up with

$f(x)=\dfrac27\ln(1+7x^2)+C$

Given that $f(0)=10$ , we have

$10=\dfrac27\ln1+C\implies C=10$

so that

$\boxed{f(x)=\dfrac27\ln(1+7x^2)+10}$

If 2(4x + 3) -12 = 3x -6, then what value of x makes the equation true ?

poizon [28]

x=0

let's solve your equation step-by-step

2(4x+3)-12=3x-6

(8x)+(6-12)=3x-6

8x-6=3x-6

subtract 3x from both sides.

8x-6-3x=3x-6-3x

5x-6+6=-6+6

5x=0

5x/5=0/5

x=0

I hope that helps you
