Answer:
D 6
Step-by-step explanation:
note that (f ○ g)(x) = f(g(x))
To evaluate f(g(x)) substitute x = g(x) into f(x)
f(g(x)) = f(4x³ + 1)
= 3(4x³ + 1)²
= 3(16 + 8x³ + 1)
= 48 + 24x³ + 3 ← polynomial of degree 6
The degree of a polynomial is the value of the largest exponent, that is 6
It cannot be 30, because the sum of two sides should be more than third side
-not D
10+18=28 <30
it cannot be 6 +10 < 18
it cannot 8
8+10=18
so it is has to be C) 12
12+18>10
10+12>18
10+18>12
answer C. 12 cm
This is how you would draw x=-6 on a graph:) (Its the red line)
You have to imagine it as (0, -6) so you would just draw that line:)
I don't know how to explain this
