given the function f defined by the formula f(x)=2x+1 fin the following: A f(4) B f(-5) C f(0) D f(1/2)

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
