The differnce quotient is basically taking the derivitive (result will be f'(x)=5, but anyway)
here is the disffernce quotient
so
for your equation
h's cancel and you are left with 5
the differnce quotient is 5
Answer:
C
Step-by-step explanation:
note y = f(x) = 0
y = 0 is the x- axis
We are looking for values of x on the x- axis where the graph crosses/touches
This occurs at
x = - 2, x = 1, x = 3 → C
Answer:
D
Step-by-step explanation:
Area of triangle= ½ ×base ×height
Since the length of the base and the height of the triangle is equivalent to the length of a side of the square, s,
area of triangle
= ½ ×s ×s
= ½s²
Given that the area of the triangle is 12.5 units²,
½s²= 12.5
Multiply both sides by 2:
s²= 12.5(2)
s²= 25
Square root both sides:
s= 5 units
(reject negative value since s > 0)
The correct answer is option C which is Gas station A is selling gasoline at a lower rate its price is $3.05 per gallon.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of numbers, variables, and functions using signs like addition, subtraction, multiplication and division.
Here we have two pieces of information
Gas station A:-
3 gallons for $9.15
1 gallons for $9.15 / 3 = $ 3.05
Gas station B:-
P = 3.08g
It means that station B is selling the gasoline at a higher price.
Therefore the correct answer is option C which is Gas station A is selling gasoline at a lower rate its price is $3.05 per gallon.

Hey there!
So, the questions stated that it wanted you to put the values in a specific format.
f(x)= P(1+r)^x
P= what is in the account R= Rate
So, we know that the account as a 4% annual interest rate. In a decimal form, that is 0.04.
Now, we can plug all the numbers in.
500(1+0.04)^x
Or, 500(1.04)^x
All we need to do to find the savings after 5 years is plug in 5 for x into a calculator.
500(1.04)^5= 608.3264512, we can round it to 608.
So, the correct answer is f(x)= 500(1.04)^x, $608
I hope this helps!
