Is y=3x+4 a function?

Oxana [17]

Answer:

Yes, it is a function

Step-by-step explanation:

Every possible input x value is paired with a unique output y value.

Another approach is to graph the function then conduct the VLT (vertical line test) at which point you will realize that any vertical line will intersect the graph at one point only meaning it is a function.

Hope this helps.

consider the following.find formula simplify answer .Find the domain for the formula and round answer to two decimal places if n

Elanso [62]

The sum of functions is given as:

$(f+g)(x)=f(x)+g(x)$

In this case we have:

$(f+g)(x)=5x+\sqrt[]{x-1}$

The domain of the functions is any number that makes the squared root a real number, then:

$\begin{gathered} x-1\ge0 \\ x\ge1 \end{gathered}$

Hence the domain of the functions is:

$\lbrack1,\infty)$

How many Children attended the classroom if there were 11 girls who made up 44% of the children?

WITCHER [35]

Answer:

Step-by-step explanation:

If 11 equals 44%, then x equals 100%.

x = $\frac{100}{44}$ * 11

11 * 100 = 1100

1100/44 = 25

So, your answer is 25.
