Answer:

In this question, we are simply taking an input value for x, which in this instance is 2, and plugging it into the function. So f(2) simply means plugging 2 into the expression and solving it. As a result, we get 3(2)^3 + 1 to solve. By order of operations we must first solve 2^3 which is 8, to get 3(8) + 1. Now, we must multiply 3*8 to get 24, and then add it to 1, to get the final answer: 25.

Step-by-step explanation:

I hope that you stick up to your word about the brainliest.

Determine whether the relations represent y as a function of x.

madam [21]

Answer:

Both of those are functions.

Step-by-step explanation:

$y=x^2$ is a parabola that opens up.

Any upward or downward parabola is a function because they pass the vertical line test.

$x=\pm \sqrt{1-y}{/tex]Square both sides:[tex]x^2=1-y$

Subtract 1 on both sides:

$x^2-1=-y$

Multiply both sides by -1:

$-x^2+1=y$

So this is a another parabola and it is faced down. So this is also a function.

$y=ax^2+bx+c$ wit $a \neq 0$ willl always be a parabola.

If $a>0$ then it is open up.

If $a$ then it is open down.

Upwards and downward parabolas will always be functions.

$x=ay^2+by+c$ are also parabolas but these open to the left or right. These will not be functions because they will not pass the vertical line test.

PLEASE HELP ASAP IM USING THE LAST OF MY POINTS

Bess [88]

The question is about rearranging the given formula to express M in terms of T,C and N:

If you subtract CN on the left and on the right, then swap it around, you get:

M = T - CN

Which is the rewritten formula for M. (Check if it makes sense: the total cost minus the monthly cost is the remaining yearly membership cost, yes that does make sense).
