 Question 629437: I need help with the following: Find p(3a-5) P(x)=-6x-10 Answer: p(3a-5)= Answer by jsmallt9(3296)   (Show Source): You can put this solution on YOUR website!p(x) = -6x-10 These problems become very easy once you get what the equation above is telling you. In that equation, the "x" in the parentheses is just a placeholder for whatever input you happen to provide to the function p. The rights side of the equation tells us what function p will do with its input (represented by the "x"): It will multiply the input by -6 and then subtract 10. Function p will do this with every input. It will multiply the input by -6 and subtract 10. p(3a-5) has "3a-5" in the parentheses, the position for the input to the function. p(3a-5) says "Use an input of 3a-5 in function p". And what does function p do with its input? It multiplies the input by -6 and then subtracts 10! p(3a-5) = -6(3a-5)-10 (Note the parentheses! Very important.) Now we simplify: p(3a-5) = -18a+30-10 p(3a-5) = -18a+20
