Answer:
F(4) = 97
Step-by-step explanation:
F(x)= x³+2x²+1
when x = 4
F(4)= 4³+2(4²)+1
= 4³+2(4²)+1
= 64 + 2(16) + 1
= 64 + 32 + 1
= 97

thank me later :)
F(x) = 2(x + 3), now if we distribute the 2, we get 2x + 6.
we know the lbs of apple is "x", and therefore, the lbs of orange will be the constant 3.
2x will then stand for the price for "x" lbs of apples.
and 2*3 will stand for the price of "3" lbs of oranges, which is 6 bucks.
since the 2 is multiplying the lbs quantity, it must then be the price, so both cost 2 bucks each per pound.
7.5 .. multiply .05 times 150
