awesome explanation hectictar! ! !
ok so here's the trick for these though:
remember just like hectictar said: "Replace every x with -2"
We know that we have a function: \(g(x) = -4x^2 -3x + 2 \)
and you also need to be very careful with PEMDAS
now! plug in -2 everywhere you see x
and solve!!
essentially just think of your g(x) as your y value.......
imagine a graph and i gave you the x coordinate (which you plugged in to your g(x) shhhh) and asked you to find the y coordinate
how would you locate the y coordinate given the x coordinate of your point? :)
but what if you were given \(f(x)=3x+5x-2+x^2\)
and told to find the \(f(-3)\)
can you tell me how that would work K19? :D
