Here are questions from my two "alter egos", Rachelle and Gusella, better known as Patti, even better known as Courtney. I am supposed to find f(g(x)). F(x)=5x^2minus 2x=3 and g(x)=4x^2 plus 7x5 The answer I got was 5(4x^2+7x5)^2+2x+3. Is this correct? Thanks!!!
I am doing the piecewise function x+3 if x is less than 2
x^2 if 2 is less than or equal to x which is less than 1, and finally, x+2 if x is greater than one. The chart says that
x x+3 (x,y)
3 0 3,0
2 1 2,1
How come the three is negative? Is there a rhyme or reason to this? Thanks!!
