The function D =25+0.3 X represents the daily dental charge D in dollars for X miles driven

Lady_Fox [76]

Answer:

See Explanation

Step-by-step explanation:

Given

$D = 25 + 0.3X$

The question has missing details; as what's required is not stated.

However, since it is a linear equation, possible questions could be

1. Determine the slope

2. Determine the D-intercept

3. Calculate the amount in dollars for (say) 5 miles

An equation is represented as:

$D = b + mx$

Where

$b = D\ intercept$

$m = slope$

By comparing: $D = 25 + 0.3X$ to $D = b + mx$

$b = 25$ and $m = 0.3$

This means that the slope is 0.3 and the d intercept is 25

To get the amount for 5 miles, we substitute 5 for x in $D = 25 + 0.3X$

$D = 25 + 0.3 * 5$

$D = 25 + 1.5$

$D = 26.5$

<em>The cost of 5 miles is $26</em>

Make use of the above explanation to solve the question

<h3>What are the output values of the x-variables?</h3>

Given the piecewise functions;

9 - x², x < 3

f(x) = {

x - 3, x ≥ 3

For x = 1, since 1 is less than 3, we use the piece of the function under x<3

f(x) = 9 - x²

f(1) = 9 - (1)²

f(1) = 9 - 1

f(1) = 8

Hence, we have a point ( 1,8 )

For x = 2, since 2 is less than 3, we use the piece of the function under x<3

f(x) = 9 - x²

f(2) = 9 - (2)²

f(2) = 9 - 4

f(2) = 5

Hence, we have a point ( 2,5 )

For x = 3, since 3 is greater than or equal to 3, we use the piece of the function under x≥3

f(x) = x - 3

f(3) = (3) - 3

f(3) = 3 - 3

f(3) = 0

Hence, we have a point ( 3,0 )

For x = 4, since 4 is greater than 3, we use the piece of the function under x≥3

f(x) = x - 3

f(4) = (4) - 3

f(4) = 4 - 3

f(4) = 1

Hence, we have a point ( 4,1 )

For x = 5, since 5 is greater than 3, we use the piece of the function under x≥3

f(x) = x - 3

f(5) = (5) - 3

f(5) = 5 - 3

f(5) = 2

Hence, we have a point ( 3,2 )

Therefore, the table of the function is;
