f(x+h) = 
Step-by-step explanation:
Given,
f(x) = 
To find the value of f(x+h) we need to replace x by x+h
Hence,
f(x+h) = 
= 
[Here, we apply the formula of
]
We need to expand the square binomial and then multiply:
<span>3x(x + 3)^2
= 3x(x + 3)</span>(x + 3<span>)
= 3x(x^2 + 6x + 9)
= 3x^3 + 18x^2 + 27x</span>
Answer:
y =-3000x +12000
Step-by-step explanation:
answer is
1) 12000 is the constant therefore when the number of hours is 0 the tickets are 12000
2) the number of tickets (y) are reducing by 3000 for each hour(x). thus the coefficient of variable x should be -3000 (negative because it is reducing)
The equation of the line is 
Explanation:
Given that the line passes through the points (-5,-3)
The slope of the line is 
We need to determine the equation of the line.
<u>Equation of the line:</u>
The equation of the line can be determined using the formula,

Let us substitute the points (-5,-3) and the slope
in the above formula.
Thus, we have;

Simplifying, we get;

Subtracting 3 from both sides of the equation, we get;

Hence, the equation of the line in slope - intercept form is
