The answer is any value that you put in for x would make the equation true. When you simplify the whole equation it looks like this: 2x - 6 = 2x - 6, therefor you could replace x with any value.

Which functions represent exponential growth? y = f(x) y = h(x) y = g(x) y = k(x).
Ymorist [56]

All are the exponential function.

<h2>Exponent</h2>

Exponential notation is the form of mathematical shorthand which allows us to write complicated expressions more succinctly. An exponent is a number or letter is called the base. It indicates that the base is to raise to a certain power. c is the base and x is the power.

<h3>Which functions represent exponential growth?</h3>

1.  y = f(x) is a exponential function.

Because the range of the exponential function is from 0 to ∞ for all values of x. And it is 1 at x = 0.

2.  y = h(x) is a exponential function.

Because the range of the exponential function is from 0 to ∞ for all values of x. And it is 1 at x = 0.

3.  y = g(x) is a exponential function.

Because the range of the exponential function is from 0 to ∞ for all values of x. And it is 1 at x = 0.

4.  y = k(x) is a exponential function.

Because the range of the exponential function is from 0 to ∞ for all values of x. And it is 1 at x = 0.

Thus, all are the exponential function.

A small business earns a profit of $6500 in January and $17,500 in May. What is the rate of change in profit for this time perio
MAXImum [283]

Rate of change of profit for this period is $2750 per month

<em><u>Solution:</u></em>

Given that,

Profit of $6500 in January and $17,500 in May

<em><u>To find: Rate of change</u></em>

Since,

January is the first month of the year (1) while May is the fifth month (5)

<em><u>Therefore, we get two points</u></em>

(1, 6500) and (5, 17500)

Using these points we can find the rate of change in profit for this time period

<em><u>The rate of change using the following formula:</u></em>

m = \frac{y_2-y_1}{x_2-x_1}

Here from the points,

(x_1, y_1) = (1, 6500)\\\\(x_2, y_2) = (5, 17500)

<em><u>Therefore, rate of change is given as:</u></em>

m = \frac{17500-6500}{5-1}\\\\m = \frac{11000}{4}\\\\m = 2750

Thus rate of change of profit for this period = $2750 per month
