The quadratic equation is given by:
y = 3x² + 10x - 8
The standard equation of a parabola is given by:
y = ax² + bx + c
Where a, b, c are constants
At point (4, 80):
80 = a(4)² + b(4) + c
16a + 4b + c = 80 (1)
At point (-3, -11):
-11 = a(-3)² + b(-3) + c
9a - 3b + c = -11 (2)
At point (-1, -15):
-15 = a(-1)² + b(-1) + c
a - b + c = -15 (3)
Solving equations 1, 2 and 3 simultaneously gives:
a = 3, b = 10, c = -8
Therefore the quadratic equation becomes:
y = 3x² + 10x - 8

<h2>
Answer:</h2>
<em>The number is </em><u><em>irrational</em></u><em>.</em>
<h2>
Step-by-step explanation:</h2>
<h3>1. Convert to decimal.</h3>

<h3>2. Conclude.</h3>
<em>Since this number shows to have infinite decimal figures, it cannot be represented as the ratio of 2 integers. Hence, the number is </em><u><em>irrational</em></u><em>.</em>
<u><em>-------------------------------------------------------------------------------------------------------</em></u>
<em>Note.</em><em> In case the number expressed in the question was </em>
, the answer would still be <u><em>irrational</em></u><em>, for the same reasons explained above</em>.
