Q.f(x) = x²(x) – x²(2) f(5) =nothing________________
f(x) = x²(x) – x²(2)
f(5) = 5²(5) – 5²(2)
f(5) = (5 × 5)(5) – (5 × 5)(2)
f(5) = 25(5) – 25(2)
f(5) = 125 – 50
f(5) = 75
Ninmy!
f(x) = x²(x) – x²(2)
f(5) = …
__
f(5) = 5²(5) – 5²(2)
f(5) = 5.5(5) – 5.5(2)
f(5) = 25(5) – 25(2)
f(5) = 125 – 50
f(5) = 75
