If f(x) = 2x²–5x+3, find f(x+1)
1 answer:
Answer:
-x
Step-by-step explanation:
To find (x+1) substitue x+1 into the function.
1. 2(x+1)^2-5(x+1)+3: Substitution
2. 2x^2+4x+2-5x+5+3: First do binominal expansion theorem for 1st one then distrubtive property for the first and second one.
3.Combine like with like
, 4x+(-5x)= -x, 2-5+3=0 so
f(x+1)= -x
