Answer:
f(x) = 4·3^x
Step-by-step explanation:
We assume the function will be of the form ...
f(x) = a·b^x
Substituting the given values, we can find 'a' and 'b'.
4/9 = a·b^(-2)
108 = a·b^3
Dividing the second equation by the first gives ...
108/(4/9) = b^(3 -(-2))
243 = b^5
b = 3 . . . . . . 5th root
Using the second equation, we can find 'a':
108 = a·3^3 = 27a
a = 108/27 = 4
The formula for the exponential function is ...
f(x) = 4·3^x
F(-3)=-2(-3)^2-5(-3)+4 <---- Plug in -3
F(-3)=-2(9)+15+4
F(-3)=-18+15+4
F(-3)=7
F(-3)=7
4/3(pi)(radius)^3 is the volume formula for a sphere, so you can use that to find the volume. Hope that helped :D
