What is true about a function?

mars1129 [50]

Answer: Your answer is the third one, a function assigns to each input exactly one output.

If you have a true function, there will only be one output for each input, if you had more than one, it isn't a function.

may someone help me ASAP? I am solving polynomial equations and I don't know how to do it, here is the equation... x^4+11x^2=3x^

koban [17]

<u>Answer:</u>

$x=2\sqrt{2}$ , $x=-2\sqrt{2}$ , $x=4i$ , $x=-4i$

<u>Step-by-step explanation:</u>

$x^4+11x^2=3x^2+128$

First, we subtract 128 from both sides:

$x^4+11x^2-128=3x^2$

Then, we subtract $3x^2$ from both sides:

$x^4+8x^2-128=0$

Rewrite the equation:

$u^2+8u-128=0$

Insert and solve:

$u^2+8u-128=0\\u=8,u=-16\\x^2=8:x=2\sqrt{2},x= -2\sqrt{2} \\x^2=-16:x=4i,x=-4i$

I just need 30 please

In the smaller triangle, let $y$ be the length of the smallest leg. Then the smallest leg in the larger triangle is $14-y$ .

Within the scope of the smaller triangle, we have $y$ such that

$x^2+y^2=13^2\implies y=\sqrt{13^2-x^2}$

Then within the larger the triangle, we would have

$x^2+(14-y)^2=15^2\iff x^2+\left(14-\sqrt{13^2-x^2}\right)^2=15^2$

Now we can solve for $x$ :

$x^2+14^2-28\sqrt{13^2-x^2}+(13^2-x^2)=15^2$

$\implies x=12$
