The function that could be represented by Rebecca’s graph is f(x) =-2(5/4)^x+3
<h3>How to determine the function that could be represented by Rebecca’s graph? </h3>
The properties are given as:
- The function is decreasing.
- The left end is approaching a constant.
For an exponential function to keep decreasing, one or more the following must be true:
- The rate is less than 1
- The leading factor is negative and the rate is greater than 1
For the left end of an exponential function to approach a constant, the following must be true:
- The leading factor is negative and the rate is greater than 1
The equation that has the above properties is f(x) =-2(5/4)^x+3
Hence, the function that could be represented by Rebecca’s graph is f(x) =-2(5/4)^x+3

Answer:
Step-by-step explanation:
(A). y = 110 , z = 63
Answer:
A = 42 cm^2
Step-by-step explanation:
To find the area of a rectangle , multiply the length and the width
A = lw
A = 7cm * 6 cm
A = 42 cm^2
Answer:
If you take 5 percent of a number and get 60, then what is that number?
In other words, you know that 5 percent of a number is 60 and you want to know what that initial number is.
To solve this problem you multiply 60 by 100 and then divide the total by 5 as follows:
(60 x 100) / 5
When we put that into our calculator, we get the following answer:
1,200
Step-by-step explanation:
Answer:
the answer is y=x+2
Step-by-step explanation:
The row of numbers beside the x each are represented by x in the equation. The equation must be true for all numbers. You must look at each number and find the pattern.
1+2= 3
2+2=4
3+2=5
each x value fits the pattern of being equal to the y value below it when adding two.
hope this helps
