The answer is C. f(n)=f(n-1)•3
Look at the photo I attached it shows how.
Hopefully this helps. This is how I was taught.
Answer:1
Reason: when you replace x with 1 in the given equation you get:
(1-1)(1+2)2(1+3)=0
0*3*2*4=0
0=0
Therefore, RHS=LHS
To graph a linear equation, you use y=mx+b. To graph a quadratic equation you use y=ax^2 + bx + c. You cannot use the same strategy to graph a quadratic equation, as in order to graph a quadratic equation, you would execute it differently. The idea is the same however, to plug numbers into the equation to find your coordinates.
Answer: x equals 4 your welcome
