Answer:

Since the input values are -7/2 and 2. So the answer is C.

Step-by-step explanation:

Given that when x-value is substituted into the function, you get 19. So in order to find the input value (x), you have to make the function equals 19 :

$f(x) = 2 {x}^{2} + 3x + 5$

$let \: f(x) = 19$

$2 {x}^{2} + 3x + 5 = 19$

Next, you have to factorize it :

$2 {x}^{2} + 3x + 5 - 19 = 0$

$2 {x}^{2} + 3x - 14 = 0$

$2 {x}^{2} + 7x - 4x - 14 = 0$

$x(2x + 7) - 2(2x + 7) = 0$

$(x - 2)(2x + 7) = 0$

Lastly, solve it :

$x - 2 = 0$

$x = 2$

$2x + 7 = 0$

$x = - \frac{7}{2}$
