Answer:
(-5 , 6)
Step-by-step explanation:
f(x) = (x - (-5))² - 3 ... vertex (h , k) : (-5 , -3) y = (x-h)² + k
g(x) = -f(x) + 3 = -((x+5)² - 3) + 3 = -(x + 5)² + 6
vertex of g(x) is : (-5 , 6)
12
the range is the difference between the highest and lowest data value
the lowest data value is zero and the highest is twelve
√21*(√3+√14)=
=√(21*3)+ √(21*14)
=√(7*3²)+ √(3*7²*2)
=3√7+7√6
