For [tex]f(x) = 3x + 4[/tex], find [tex]f(2)[/tex] and find [tex]x[/tex] such that [tex]f(x) = 17[/tex].

To solve for f(2) using the function f(x) = 3x + 4 , we simply substitute x with 2. The calculation will be f(2) = 3(2) + 4 = 6 + 4 = 10 . So, f(2) is 10.
To find the value of x such that f(x) = 17 , we set up the equation 3x + 4 = 17 . Solving for x , we subtract 4 from both sides to get 3x = 13 , and then divide both sides by 3, giving us x = ∓ 13∓ or approximately x = 4.333 . So, the value of x such that f(x) = 17 is approximately 4.333 or 13/3 in fraction form.
