The topic is about operations on functions: composition and transformation

telo118 [61]

Answer:

5, 1, 5, 1.

Step-by-step explanation:

take it one step at a time.

for the first one f(g(1))

first do whats inside of the parenthesis.

> g(1), go to g(x) graph, go to x= 1 and your y-value is your new value (3)

> your new equation is now f(3)

→ go to f(x) graph, go to x= 3, your y-value is 5. Your final answer is 5.

Question 5 (4 points) Marijuana was recently legalized in Canada. A recent study reported that at low doses marijuana could have

Makovka662 [10]

Using the coefficient of variation, it is found that students were more variable in their marijuana consumption.

<h3>What is the coefficient of variation of a data-set?</h3>

The coefficient of variation of a data-set is given by the <u>division of the standard deviation of the data-set by the mean of the data-set</u>. The higher the coefficient, the more variable the data-set is.

In this problem, for marijuana consumption, the average was 3.74 and the standard deviation was 1.47, hence:

$CV_m = \frac{1.47}{3.74} = 0.393$

For depression levels, the average was 19.32 and the standard deviation was 3.18, hence:

$CV_d = \frac{3.18}{19.32} = 0.166$

Due to the higher coefficient, students were more variable in their marijuana consumption.

The function f(x) = −x2 + 50x − 264 models the profit, in dollars, a yoga studio makes for selling monthly memberships, where x

Marina CMI [18]

The given function is $f(x) = -x^2 + 50x - 264$ . This is a quadratic function because the degree of the polynomial, the variable with the highest exponent, is 2.

All quadratic functions can be expressed in the form $f(x) = ax^2 + bx + c$ .
In your equation,
a = -1
b = 50
c = -264

The equation for the x-coordinate vertex of a quadratic function is $x = \frac{-b}{2a}$ .
Applying this to the given function,
$x = \frac{-(50)}{2(-1)} = \frac{50}{2} = 25$ .

Now plug the value of x into f(x) to find f(x) (aka the y-coordinate).
$f(x) = -x^2 + 50x - 264 \\
f(25) = -(25)^2 + 50(25) - 264 \\
f(25) = 361$

The vertex is (25, 361)

Part B
The x-intercept is where the graph crosses the x-axis. Therefore, f(x) (aka the y-coordinate) will be 0. So the x-intercept will be in the form of (x, 0).

To find the x-intercept, set f(x) = 0.
$0 = -x^2 + 50x - 264 \\
0 = (x-6)(x-44) \\
x = 6, x = 44$ .

Therefore the x-intercepts will be at (6, 0) and (44, 0)
