(f.g)(x) = f (g(x))= f ( x^4+3)
= (x^4+3)^2 + 2 ( x^4+3) - 6
= x^8 + 9 + 6x^4 + 2x^4 + 6-6
= x^8 + 8x^4+9
Answer:

Step-by-step explanation:




The equation for C in terms of t,t, representing the total cost of the gym membership over tt months is C = 150 + 50t
<h3>Equation</h3>
There are three basic types of equation in mathematics. Namely:
- Linear equations
- Quadratic equations
- Simultaneous equations
- Monthly fee = $50
- One-time joining fee = $150
- Total cost = C
- Number of months = t
C = 150 + 50t
Therefore, the equation for C in terms of t,t, representing the total cost of the gym membership over tt months is C = 150 + 50t
