Answer:
Option (a) is the correct choice.
The result of the given function 
at x = 3 is -28
Detailed explanation:
Provided: Function
We need to calculate the function's value at x = 3
Evaluate the specified function
As we are required to find the function's value at x = 3
Substitute x = 3 into the function f(x)
Upon simplification, we get
Thus, the value of the given function at x = 3 is -28
Answer : y>0
f(x) = 9*2^x
This function is exponential in form
Substituting positive numbers for x yields positive y values
Substituting negative numbers for x also results in positive y values
Therefore, y remains positive regardless of the value of x.
The range comprises all possible y outputs of the function
Since y is always positive, the range is y > 0
Response: The properties of mathematical operations assist in solving integer-related problems as they provide various methods to arrive at the solution.
Step-by-step explanation:
Answer:
40 * x - 600 = 0
Step-by-step explanation:
Initially, identify the variable (x) in the equation, representing the number of days it takes Leilah to review her flashcards. To study 600 out of her 2400 cards, having gone through 1800 already, we arrive at:
2400 - 1800 = 40 * x
rearranging leads to
40 * x - 600 = 0
This equation describes the situation above
