Answer:
1.
y = 20(11) + 300 = 520
y = 5(11)(11) = 605
y = 10(1.4)^11 = 404.96
hence the quadratic formula - y = 5x^2 has the largest y-value
2.
y = 20 (14) + 300 = 580
y = 5 (14) (14) = 980
y = 10(1.4)^ 14 = 1111.20 > this is greater than both equations above
14 is the smallest value of x for which the value of the exponential equation is greater than the values of both the linear and quadratic functions

Answer:
C 
Step-by-step explanation:
Hello,
The method is to find the roots of the denominator.
x²-2x-15=x²+3x-5x-15=x(x+3)-5(x+3)=(x+3)(x-5)
Roots are x=-3 and x=5
