Evaluate the composite function a ( b ( y ) ) a\left(b\left(y\right)\right) a ( b ( y ) ) given the following: a ( x ) = x 2 a\left(x\right)=x^2 a ( x ) = x 2 b ( x ) = x 2 − 7 b\left(x\right)=x^2-7 b ( x ) = x 2 − 7

y 4 − 14 y 2 + 49 y^4-14y^2+49 y 4 − 14 y 2 + 49

y 2 − 14 y + 49 y^2-14y+49 y 2 − 14 y + 49
