We have the following function:
f (x) = 4 * ((81) ^ (1/3)) ^ x
We observed that:
(81) ^ (1/3) = 4.326748711> 1
Therefore the function grows as it increases and decreases as x decreases.
We have then:
Domain: all reals.
Range: all reals greater than zero.
Answer:
A) {x | x is a real number}; {y | y> 0}
Answer:
51 + 29+ 80
Step-by-step explanation:
she got this by adding 51 + 29
Answer:it the first two
Step-by-step explanation:
Correct answers are A and B.
The more precise answers are the numbers which could be rounded to 180. Those are 180.4 and 175.
F(x) = 2(x)^2 + 5 * sqrt(x + 2)
f(2) = 2(2)^2 + 5 * sqrt(2 + 2)
f(2) = 2 * 4 + 5 * sqrt(4)
f(2) = 8 + 5 * 2
f(2) = 8 + 10
f(2) = 18
