Complete the algebraic expression. I'm having trouble understanding how to do this, could use some help.

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)

(mc 02.03) what set of reflections and rotations would carry rectangle abcd onto itself? reflect over the y-axis, reflect over the x-axis, rotate 180° rotate 180°, reflect over the x-axis, reflect over the line y=x reflect over the x-axis, rotate 180°, reflect over the x-axis rotate 180, reflect over the y-axis, reflect over the line y=x

Through non-collinear points there is exactly one plane.
