f(x)=x2+x𝑓(𝑥)=𝑥2+𝑥 f(−2)=𝑓(−2)= Answer 1 Question 18

f(x)=x2+3x𝑓(𝑥)=𝑥2+3𝑥f(−4)=

Given the function 𝑓(𝑥)=−2𝑥2−20𝑥−51, find  f(-2).

b) f(x) = 3𝑥2;     𝑑𝑓𝑑𝑥(1)= therefore the function is

Suppose that 𝑓 and 𝑔 are continuous functions and that 𝑓 is an odd function, i.e. 𝑓(−𝑥)=−𝑓(𝑥) for all 𝑥.Find ∫25(𝑓(𝑥)+5𝑔(𝑥))𝑑𝑥 given that∫−52𝑓(𝑥) 𝑑𝑥=9 and ∫25𝑔(𝑥) 𝑑𝑥=-2.
