What is the domain of the square root function graphed below?

IrinaK [193]

we know that

<u>The domain</u> of the function graphed is the interval-------> [3,∞)

$x\geq 3$

that means

All real numbers greater than or equal to $3$

<u>The range</u> of the function graphed is the interval --------> [1,∞)

$y\geq 1$

that means

All real numbers greater than or equal to $1$

therefore

the answer is the option

$x\geq 3$

If f(x) = g(x+1) and g(x) = x^2, find the value of f(3).

Elena-2011 [213]

$\bf \begin{cases} f(x)=&g(x+1)\\ f(3)=&g(3+1)\\ &g(4)\\[-0.5em] \hrulefill& \hrulefill\\ g(x)=&x^2\\ g(4)=&4^2\\ &16 \end{cases}\qquad \qquad f(3)\implies g(4)\implies 16$

Find sin θ and cos θ where θ is the angle that corresponds to the point P (5,12)

xxTIMURxx [149]

Check the picture below.

$\bf P~(\stackrel{a}{5}~~,~~\stackrel{b}{12})\qquad \impliedby \textit{let's find the hypotenuse} \\\\\\ \textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2\implies c=\sqrt{a^2+b^2} \qquad \begin{cases} c=hypotenuse\\ a=adjacent\\ b=opposite\\ \end{cases}$

$\bf c=\sqrt{5^2+12^2}\implies c=\sqrt{25+144}\implies c=\sqrt{169}\implies c=13 \\\\[-0.35em] ~\dotfill\\\\ ~\hfill sin(\theta )=\cfrac{\stackrel{opposite}{12}}{\stackrel{hypotenuse}{13}}\qquad \qquad cos(\theta )=\cfrac{\stackrel{adjacent}{5}}{\stackrel{hypotenuse}{13}}~\hfill$
