The function f(x) = 2x2 + 3x + 5, when evaluated, gives a value of 19. What is the function’s input value?

iren2701 [21]

F(x)......ur output = 19

19 = 2x^2 + 3x + 5
2x^2 + 3x + 5 - 19 = 0
2x^2 + 3x - 14 = 0
(2x + 7)(x - 2) = 0

2x + 7 = 0
2x = -7
x = -7/2

x - 2 = 0
x = 2

I believe there is 2 possible answers......x (ur input value) = -7/2 or 2
