x = 1.54 or x = - 4.54 to 2 decimal places

Step-by-step explanation:

x² + 3x - 7 = 0

Using the quadratic formula

a = 1 b = 3 c = - 7

$x = \frac{3 ± \sqrt{ {3}^{2} - 4(1)( - 7) } }{2(1)} \\ x = \frac{ - 3± \sqrt{9 + 28} }{2} \\ \\ x = \frac{ -3 ± \sqrt{37} }{2} \\ \\ x = \frac{ - 3 + \sqrt{37} }{2} \: \: \: \: \: or \: \: \: x = \frac{ - 3 - \sqrt{37} }{2} \\ \\ x = 1.54 \: \: \: or \: \: x = - 4.54$

Hope this helps you

No graph is attached, so I’ll start with the largest slope (rate of change) to the lowest

1/4 = 0.25x
1/3 = 0.33x
3/10 = 0.3x
2/5 = 0.2x

Therefore, from largest to smallest slope,
D -> A -> C -> B
