Step-by-step explanation:
The rate of change is defined as the derivative of the function, or also known as the slope. The derivative here would be 3. Another function which has the same rate of change would be any function with a slope of 3. A few example are:
f(x) = 3x + 1
f(x) = 3x + 2
 
        
             
        
        
        
Answer:
Jake:y
grandma:6y
cousin:y+5
the sum of all their ages:8y+5
Step-by-step explanation:
