Answer:
Step-by-step explanation:
Substitute x = 2 into both h(x) and f(x)
h(2) = = 1 ⇒ (h(2))² = 1
f(2) = 2 + 2 = 4
Hence
when x = 2
=
Answer:
Between 67 and 103 beats per minute
Step-by-step explanation:
The minimum would be 80. That means that the minimum sum would have to be 320 among the four numbers.
85+81+87=253
320-253=67 so 67 will be the minimum
now, we should see the maximum. It will be 89 so the sum of the four numbers cannot be anymore than 89*4 which is 356
So, 356-253=103
Answer:
hello :
the graph passes by ( 3; -1/3) : f(3) = -1/3
a/ (3)^3 = -1/3
a / 27 = -1/3
a/9 = - 1
a = - 9
