Answer:

f(-142)

x(-0.2(x+223)

firstly we are to find f of x and this is by multiplying the f value by the x value

fx = (-142)(-0.2(x+233)

=( -142)(0.2x+-446)

=28.4x +63332

28.4x=63332

now you divide both sides by the x variable

28.4x/28.4 =63332/28.4

=-2230

I'm not sure about this answer so please make sure to ask an expert
