Answer:
a^11
Step-by-step explanation:
a to the power of 2 to the power of 3 equals to a to the power of 6
then, multiplied to a to the fifth, you add 5 by 6, which is 11
Answer:
D (assuming f(x)=-3x^2+4x+6)
Step-by-step explanation:
Let's find f(2) and f(3).
I'm going to make the assumption you meant f(x)=-3x^2+4x+6 (please correct if this is not the function you had).
f(2) means replace x with 2.
f(2)=-3(2)^2+4(2)+6
Use pemdas to simplify: -3(4)+4(2)+6=-12+8+6=-4+6=2.
So f(2)=2
f(3) means replace x with 3.
f(3)=-3(3)^2+4(3)+6
Use pemdas to simplify: -3(9)+4(3)+6=-27+12+6=-15+6=-9
So f(3)=-9
-9 is smaller than 2 is the same as saying f(3) is smaller than f(2) or that f(2) is bigger than f(3).
The question here is a little unclear. Would love to help but please clarify :)
