Answer:
fg(x) = 32x²+44x+16
Step-by-step explanation:
fg(x) = f[g(x)]
= f(4x+3)
= 2(4x+3)²-(4x+3)+1
= 2(4x+3)²-(4x+3)+1
= 2(16x²+24x+9)-4x-3+1
= 32x²+44x+16
1200 mL, if 300 is half of half the container, that means half is 600 mL, so 600×2=1200
For the first one, the fraction version for 0.25 is 1/4 and the percentage is 25%
