What is a function?

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

The function is given below.

[tex]f(x) = \sqrt{x}[/tex]

For x = -1, then the value of the function f(x) will be

[tex]f(-1) = \sqrt{-1}[/tex]

The function is not defined as a negative value.

For x = 0, then the value of the function f(x) will be

[tex]f(0) = \sqrt{0}=0[/tex]

For x = 1, then the value of the function f(x) will be

[tex]f(1) = \sqrt{1}=1[/tex]

For x = 4, then the value of the function f(x) will be

[tex]f(4) = \sqrt{4}=2[/tex]

HELPPP! ALMOST DUE! Clara estimated that her brother is 4 feet tall. When they get measured at the doctor’s office, her brother’s actual height is 4 feet, 2 inches. What was the percent error for Clare’s estiamate? PLZ HELP!!!

Answers

Answer:

Her error in terms of inches was 2 inches while her percent error was 4.166%

Step-by-step explanation:

From the given data Claire estimated her brother to be shorter than he actually was. She estimated his height to be 4 feet while it was actually 4 feet 2 inches.

We convert the feet into inches because 12 inches are equal to a feet.

4 feet = 4 × 12 inches = 48 inches

4 feet 2 inches = (4 × 12 inches) + 2 inches = 48 + 2 = 50 inches

Error in terms of inches = 50 inches - 48 inches = 2 inches.

Step 2 ; Her percent error is given by dividing the difference in values by the actual value multiplied by 100.

% error = (difference in values / actual value) × 100

Claire's % error = (50 - 48)/ 48 × 100 = 2/48 × 100 = 0.04166 × 100 = 4.166%

Answer:

A 4% difference

Step-by-step explanation:

Convert 4 feet 2 into 4.16666666

4/4.16666666= 0.96 or 96%

4 feet was 96% of 4 feet 2 in

100 - 96= 4%

And this shows that there was a 4% error.
