Please solve i and ii for me
KengaRu [80]

If you know the derivative f'(x) of some function f(x), you can tell exactly who f(x) is, up to an additive, constant term. In fact, knowing f'(x), you have

\displaystyle \int f'(x) = f(x)+c

In your case, we have

\dfrac{d}{dx} \sqrt{x+3} = \dfrac{1}{2\sqrt{x+3}}

So, the integral is almost immediate:

\displaystyle\int \dfrac{2}{\sqrt{x+3}} = \int \dfrac{4}{2\sqrt{x+3}} = 4\int\dfrac{1}{2\sqrt{x+3}} = 4\sqrt{x+3}+c

So, up to some constant additive term, our function is 4\sqrt{x+3}+c

To fix this constant, we know that the function passes through the point (6,10), so we have

f(6) = 4\sqrt{6+3}+c = 4\sqrt{9}+c=12+c=10 \iff c=-2

And so our function is 4\sqrt{x+3}-2

If we want to know when this function equals 6, we simply have to ask f(x)=6 and solve for x, so we have

4\sqrt{x+3}-2=6 \iff 4\sqrt{x+3} = 8 \iff \sqrt{x+3} = 2 \iff x+3=4 \iff x = 1
