Hello from MrBillDoesMath!
Answer:
The second choice, [1,2]
Discussion:
The key to this question is that we are looking for "local maximum". In the graph a local maximum, think "camel hump", occurs in the interval [1,2] -- but the global maximums, if there is one, appears to occur in x > 3 and x < -1
Thank you,

Answer:
9x^4 -x
Step-by-step explanation:
( -8x + 3x^4 ) - ( -7x - 6x^4 )
Distribute the minus sign
( -8x + 3x^4 ) +7x + 6x^4
Combine like terms
3x^4 + 6x^4 -8x +7x
9x^4 -x
