Which of the following functions maps 3 to -5? O f(x) = -x + 2
O f(x) = x-5
O f(x) = x + 8
O f(x) = 4 – x²

F(x)=x-5

Step-by-step explanation:3 to -5 x values the 3 and then the -5 is already there. PLUS I DID THE TEST

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
