Please I need help with this algebra problem

Question

With the 3 equations
f1(x)=0
f2(x)=1/8(x+16)^2-98
f3(x)=2x+24

Determine an equation for this function with the 3 pieces above.(Refer to creating the polynomial functions)

Answer 1

no idea what you want to do.

We could make

g(x) = f2(x) - f3(x)

or whatever you want to do. What do you mean when you say "this function"?

Answer 2

thats where I'm stuck at

Answer 3

i have even seen an example like this in the lesson

Answer 4

how would i minus the f(2)x by f(3)x

Answer 5

oh please - just use their definition!

f2(x) - f3(x) = (1/8 (x+16)^2-98) - (2x+24)

You might want to simplify that to

x^2/8 +2x -90
