What effects does adding a constant have to an exponential function?

Mathematics
1 answer:
Stells [14]3 years ago
5 0
It depends where you introduce constant 

Exponential function: f(x) = e^x 

y = e^x + c ----> shift function up c units 
y = e^(x−c) ----> shift function right c units 
y = e^(cx) ------> dilates function horizontally by factor of 1/c 
y = c e^x -------> dilates function vertically by factor of c

In a group of 60 students, 20%are girls. How many are boys?
Firlakuza [10]

Answer: About 12 of those 60 students are boys.

To find the percent, you'll convert 20% to a decimal.

20 / 100 = 0.2

Then, multiply 60 by 0.2

0.2 × 20 = 12

That's one way, another way is:

Convert 20% to a fraction.

20% = 1/5

Then multiply 60 by 1/5.

60 × 1/5 = 60/5

Lastly, divide 60 by 5

60 / 5 = 12.

Hence, 12 is the answer.

- The ANOVA (Analysis of Variance) F test

- Plot residuals against fitted values

(B) Checking the Normal Assumption, the appropriate techniques to use are:

- Test for Kurtosis & Skewness

- Kolmogorov-Smirnov Test

- Q-Q Plots (the graphical method) also known as Quantile Plot

- Do not use a histogram; it is not advisable

(C) Checking for Model Misspecification, the appropriate techniques to use are:

- The Ramsey Regression Specification Error Test; also called RESET

In the figure below, the value of x is:<br> who ever show works gets brainlly
blondinia [14]

Answer:

d)  x  = 72°

Step-by-step explanation:

Corresponding Angles:   The pair of angles formed on the same side of traversal which crosses two parallel lines is called a pair of corresponding angles.

These angles are EQUAL to each other.

Now, here in the given figure:

The two below lines are parallel to each other.

Also, the line crossing it on the right side forms a traversal.

So angle x and angle with 72 degrees form a pair of Corresponding Angles.

⇒ x  = 72°

Hence the measure of angle x  = 72°
