Step-by-step explanation: ∆y/∆x =1-½/2-1=½ the first part of the rule is ½x Plug in x=3 ½×3=3/2 when x=5 ½×5=4/2 Therefore the rule is y=½x+0
Answer from: Quest
problem:
f(x) = - 2/3x + 5; f(5/2)
substitute 5/2 in for x:
f(5/2) = -2/3(5/2) + 5
simplify the right side:
f(5/2) = -5/3 + 5
f(5/2) = 10/3
f(5/2) = 10/3
i hope this !
