A function is a relation that has one output for a given input.

For the first one, there is no one x value with two or more y values so it is a function.

The second example is also a function because a certain value can only have one cube root.

For problem number 3 input "-3" for every instance of x in h(x).

So, h(-3)=2(3^2)-1= 17

Answer:

$- 2x + 28$

Step-by-step explanation:

1) Expand by distributing terms.

$- 2x - 2 \times - 14$

2) Simplify 2 × -14 to -28.

$- 2x - ( - 28)$

3) Remove parentheses.

$- 2x + 28$

Therefor, the answer is - 2x + 28.

Find the range of the function:

-BARSIC- [3]

F(x) = x + 2
when x = 1, f(1) = 1 + 2 = 3
Therefore range for x ≠ 1 is y ≠ 3.

<h2>Hello!</h2>

The answer is:

The second option,

b.) $C(x)=40.60x+201$

We are given the functions E(x) and K(x), since they both are function of the same variable, we need to add them in order to find the correct option.

From the statement we know the functions:

$E(x)=22.75x+74$

and

$K(x)=17.85x+127$

So, adding the functions we have:

$C(x)=E(x)+F(x)$

$C(x)=(22.75x+74)+(17.85x+127)$

$C(x)=22.75x+17.85x+74+127$

$C(x)=40.60x+201$

Hence, the answer is the second option,

b.) $C(x)=40.60x+201$

Have a nice day!
