Hey there!!!
Equation given :
p ( x ) = 3x² + 4x + 5
Find p ( 2x )
In order to solve this, we will have to substitute the value 2x instead of x
Hence,
... p ( 2x ) = 3 ( 2x )² + 4 ( 2x ) + 5
... p ( 2x ) = 3 ( 8x² ) + 8x + 5
... p ( 2x ) = 24x² + 8x + 5
As we know I ( x ) = p ( 2x )
The value of I(x) = 24x² + 8x + 5
Hope my answer helps!

Answer:
3
Step-by-step explanation:
24 + (-1) = 23, 12 + (-2) = 10, 8 + (-3) = and 6 + (- 4) = 2, none of the sums are equal to 3, therefore b = 3 would give a prime quadratic. The correct answer is then A. 3
