So I have tried both approaches on this now. The question says to solve the equation. Initially I tried solving for x (i got-1/4), that was wrong. Then I tried just putting 0.5 into the equation (I got 5) and that was wrong aswell. I have no clue what this question is asking me

i assume besides c) its 2 * P of x

if we divide the two sides by two in the first equation then P(x) is now equal to 0.25

then we replace P(x) with its equivalent formula, such that 3x + 1 = 0.25, then we subtract 1 on both sides such that -0.75 and then we divide by 3 such that x = -0.25

then we can test it 2 * P(-0.25) = 2 * (3 * -0.25 + 1) = 2 * (-0.75 + 1) = 2 * 0.25 = 0.5

so in this case x = -0.25

#

how did you come to the conclusion that -(1/4) was wrong?
