Answer:
$0.23 or D
Step-by-step explanation:

We could put the domain into the x values to get the y values (range).
y = 3(-3) - 4
y = -9 - 4
y = -13
y = 3(-1) - 4
y = -3 - 4
y = -7
y = 3(4) - 4
y = 12 - 4
y = 8
You have to figure out X by going one through 10 Once you figure it out you multiply 4 times that number and then you subtract one and you’ll get seven like 4 x 2= 8-1= 7
X^3 - 21x = -20add 20 to both sidesx^3 - 21 x + 20 = 0Rational Root Theorem:Factors of P (constant) 20 = 1, 2, 4, 5, 10, 20------------------------------- Factors of Q (leading Coefficient) = 1
Possible zeros (all + -) 1/1, 2/1, 4/1, 5/1, 10/1, 20/1
Of the choices given only the number 1 is a possible root.
(4^7/5^2)^ 3
= 4^21 / 5^6
which according to my calculator is 281,474,976.7 approximately
