Web19 jul. 2024 · If the equation is f (x) = 2x 2+1 and X=3 Then you you would plug 3 in for x and solve following the order of operation. Exponent first, then Multiplication, and then Addition. f (3) = 2 (3) 2+1 = would be (3) 2 = 2x9+1 = 18 + 1 = 19 therefore f (3) = 19 Upvote • 0 Downvote Add comment Report Brenda D. answered • 07/19/20 Tutor 5 (6) Web9 mrt. 2024 · if $f (x + 3) = 2x^2 - 3x - 1$ find $f (x + 1)$.
