Let f(x) = 2x, g(x) = 2x2 – x, and h(x) = 3x. lola finds the composition [f o g o h](x) as shown below. what error did lola make?

= 2[2(3x)2 – 3x]
= 2[2(9x2) – 3x]
= 2(18x2 – 3x)
= 36x2 – 3x

Asystem of equation is shown below 6x - 2y equals 3 . and 5x + 3y equals 4. would you solve by substitution or elimination? and why
