Answer:

x | -1 | 0 | 1 | 2 | 3

y | -7 | -4 | 3 | 14 | 29

Explanation:

To complete the table of values, y = 2x^2 + 5x - 4,let's substitute each given x-value into the equation and solve for y.

Let's calculate the corresponding y-values for each x-value :

When x = -1:-

$\sf y = 2* (-1)^2 + 5* (-1) - 4\\\\ = 2* 1 - 5 - 4\\\\ = 2 - 5 - 4\\\\=\boxed{ -7}$

When x = 0:

$\sf y = 2* (0)^2 + 5*(0) - 4\\ \\= 0 + 0 - 4\\ \\=\boxed{ -4}$

When x = 1:

$\sf y = 2* (1)^2 + 5* (1) - 4 \\ \\= 2* 1 + 5 - 4 \\\\= 2 + 5 - 4 \\\\=\boxed{ 3}$

When x = 2:

$\sf y = 2* (2)^2 + 5* (2) - 4\\\\ = 2*4 + 10 - 4\\\\ = 8 + 10 - 4\\ \\= \boxed{14}$

When x = 3:

$\sf y = 2* (3)^2 + 5* (3) - 4\\\\= 2* 9 + 15 - 4\\\\= 18 + 15 - 4 \\\\=\boxed{ 29}$

Therefore, the completed table of values is as follows:

x | y

-1 | -7

0 | -4

1 | 3

2 | 14

3 | 29
