Considering the given linear function, we have that:

The change for each copy that he sells is of $120.

If he sells no copies, he makes $2400.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.

b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

His payment for x copies bought is:

y = 120x + 2400.

Hence:

The change for each copy that he sells is of $120, as the slope is of $120.

If he sells no copies, he makes $2400, which is the y-intercept.

Draw a model or use numbers to solve the equation 3+x=<br> 11. What is the solution?

Stolb23 [73]

Answer:

The solution of the equation $3 + x = 11$ is $x = 8$ .

Step-by-step explanation:

Let $3 + x = 11$ , we see that number of equation and variables are both the same and can be solved by algebraic means.

1) $3 + x = 11$ Given

2) $x + 3 = 11$ Commutative property

3) $x + [3+(-3)] = 11 + (-3)$ Compatibility with addition/Associative property

4) $x = 8$ Additive inverse/Modulative property/Definition of substraction/Result

The solution of the equation $3 + x = 11$ is $x = 8$ .

Given a polynomial function f(x) = 2x2 – 3x + 5 and an exponential function g(x) = 2% – 5, what key features do f(x) and g(x) ha

prohojiy [21]

A. Both $f(x)$ and $g(x)$ have the <em>same</em> domain of $(9, +\infty)$ .

<h3>How to analyze similarities in two functions</h3>

In this question we must analyze the domain, range, x-intercepts and <em>increase</em> intervals:

<h3>Domain</h3>

$Dom \{f(x)\} = \mathbb{R}$

$Dom \{g(x)\} = \mathbb{R}$

Both functions are <em>continuous</em>.

<h3>Range</h3>

$Ran \left\{f(x)\right\} = (3.875, +\infty)$

$Ran \{g(x)\} = (-5, +\infty)$

<h3>x-Intercepts</h3>

$f(x):$ $(x,y) = \emptyset$

$g(x):$ $(x,y) = (2.322, 0)$

<h3>Increase intervals</h3>

$f(x):$ According to the graph, $f(x)$ increase over the interval of $(3.875, + \infty)$ .

$g(x) :$ According to the graph, $g(x)$ increase over the interval of $\mathbb{R}$

After a quick analysis, we conclude that option A offer the best approximation to characteristics of both functions. $\blacksquare$

<h3>Remark</h3>

The statement presents mistakes and is poorly formatted. Correct form is:

<em>Given a polynomial function </em> $f(x) = 2\cdot x^{2}-3\cdot x + 5$ <em> and an exponential function </em> $g(x) = 2^{x}-5$ <em>. What key features do </em> $f(x)$ <em> and </em> $g(x)$ <em> have in common? </em>

<em />

<em>A.</em><em> Both </em> $f(x)$ <em> and </em> $g(x)$ <em> have the same domain of </em> $(9, +\infty)$ <em>.</em>

<em>B.</em><em> Both </em> $f(x)$ <em> and </em> $g(x)$ <em> have the same range of </em> $(-\infty, 0]$ <em>.</em>

<em>C.</em><em> Both </em> $f(x)$ <em> and </em> $g(x)$ <em> have the same x-intercept of </em> $(2,0)$ <em>.</em>

<em>D.</em><em> Both </em> $f(x)$ <em> and </em> $g(x)$ <em> increase over the interval of </em> $(-4, +\infty)$ <em>.</em>
