This is a quadratic equation, which is also a polynomial. Polynomials all have the domain (-infinity, +infinity).
As for the range: You can see from the graph that the smallest y-value is -2. Thus, the range is [-2, infinity).
Answer: 48,60
Step-by-step explanation:
4x+5x=108
9x=108
x=108/9=12
12•4=48
12•5=60
Answer:
5 is the answer
Step-by-step explanation:
For trapezoid, the area = (upper base + lower base) * height / 2
So area = (12 + (2*2 + 12) ) *13 / 2 = 182
