Cubic Function
Step-by-step explanation:
In mathematics, a cubic function is a function of the form f(x)=ax^3+bx^2+cx+d where the coefficients a, b, c, and d are real numbers, and the variable x takes real values, and a ≠ 0. In other words, it is both a polynomial function of degree three, and a real function.

Answer:
12
Step-by-step explanation:
b-4x
Plug in 4 as b and -2 as x

Two negatives make a positive
= 4+8
= 12
I hope this helps!
Answer:
= 270 ⇒ Last answer
Step-by-step explanation:
* If f(x) = 7 + 4x
* If g(x) = 
* We want to find 
- Lets find at first 
∵ f(x) = 7 + 4x
∵ g(x) = 
∴ 
- Lets divide the numerator by the denominator
∵ The numerator is 7 + 4x
∵ The denominator is 
∴ (7 + 4x) ÷ 
- Lets reverse the division sign to multiplication sign and reciprocal
the fraction after the division sign
∴ (7 + 4x) × 
∴
= 2x(7 + 4x)
∴
= 14x + 8x²
- Now substitute x by 5
∴
= 14(5) + 8(5)² = 70 + 200 = 270
∴
= 270
