is the given function continuous at x=1?
[tex]f(x) = 2x {}^{2} - 3x + 1[/tex]
A. No since the value of the function at x = 1 is 4
B. No since the function is undefined at x=1
C. Yes since the function is defined at x=1
D. Yes since the value of the function at x=1 is 4
Answers
Answer:
The answer is "Option C".
Step-by-step explanation:
Given:
[tex]\to f(x)=2x^2-3x+1\\\\when \ x=1\\\\\to f(1)= 2(1)^2-3(1)+1\\\\\to f(1)= 2(1)-3+1\\\\\to f(1)= 2-3+1\\\\\to f(1)=-1+1\\\\\to f(1)=0[/tex]
That's why choice C is correct.

Giselle is going to rent a scooter for at least one
hour. The fee is $45 plus $5 for each hour tis
rented. Write a function rule to describe the total
cost of renting a scooter Find a reasonable domain
and range for the functon (Gisele has $65
Answers
Answer:
Step-by-step explanation:
Cost of rental: f(t) = 45 + 5t, where t is the hours of rental
The cost cannot exceed $65.
f(t) = 45+5t ≤ 65
5t ≤ 20
t ≤ 4 hours
Minimum rental time is 1 hour, so minimum charge is f(1) = 45+5·1 = 50
Domain: {1,2,3,4}
Range: {50,55,60,65}

Step-by-step explanation:
we are given a function and the inputs (x)
so we just need to substitute the values of inputs (x) to the function and simplify
our given function:
[tex] \displaystyle \: f(x) = \frac{x}{2} - 1[/tex]
when x is -2 then
[tex] \displaystyle \: f( - 2) = \frac{ - 2}{2} - 1[/tex]
simplify division:
[tex] \displaystyle \: f( - 2) = - 1 - 1[/tex]
simplify subtraction:
[tex] \displaystyle \: f( - 2) = - 2[/tex]
when x is 0 then
[tex] \displaystyle \: f(0) = \frac{0}{2} - 1[/tex]
simplify division:
[tex] \displaystyle \: f(0) = 0 - 1[/tex]
simplify substraction:
[tex] \displaystyle \: f(0) = - 1[/tex]
when x is 4 then
[tex] \displaystyle \: f(4) = \frac{4}{2} - 1[/tex]
simplify division:

A newspaper reported the results of a Valvoline Oil Company survey of 500 drivers in which the drivers marked their complaints about other drivers. The top complaints turned out to be tailgating, marked by 22% of the respondents; not using turn signals, marked by 19%; being cut off, marked by 14%; other drivers driving too slowly, marked by 9%; and other drivers being inconsiderate marked by 5%.

The length of a rectangular garden is 17 feet longer than its width. If the area of the garden is 234 square feet, what are the dimensions of the garden?
Answers
Answer:
The garden is 9 feet wide and 26 feet long.
Step-by-step explanation:
L = W+17
area = LW = 234
(W+17)W = 234
W²+17W-234 = 0
Quadratic formula
W = [-17 ± √(17² – 4·1(-234))] / [2·1]
= [-17 ± √1225] / 2
= [-17 ± 35] /2
= -26, 9
-26 is an extraneous solution
W = 9
L = W+17 = 26
The garden is 9 feet wide and 26 feet long.

When she dived down low
