) Consider the following function: f₁ R → R given by f₁(x): Decide whether this function is injective, surjective, a bijection. fi is an injection: Not Answered fi is a surjection: Not Answered f₁ is a bijection: Not Answered = -3x4 - 5. ) Let the set A = {-1,0, 1} and consider the following function: f₂ : A → A given by f₂(x) = -(-x)³. You are required to state whether this function is injective, surjective, a bijection. f2 is an injection: Not Answered f2 is a surjection: Not Answered f2 is a bijection: Not Answered

Graph f(x)=2x10. Picka set of5 ordered pairs using inputs x=2,1,5,6,9 and use linear regression to verify the function.

For the function h(x)=2x+1 , evaluate the function. (a) h(k2) (b) h(x+1) (c) h(x)+h(1)

Find the domain of the function, f(x)45x. Write the domain in interval notation.
