F, g,h: r -> r, f(x) = 3x + 7,g(x) =x - 4,h(x) =x 2 + 1. instead of x 2 , you may use: x * x determine f o g and h o g (evaluate completely and combine like terms).

  f(g(x)) = 3x -5

  h(g(x)) = x^2 -8x +17

Step-by-step explanation:

— f(g(x))

  f(g(x)) = f(x -4) = 3(x -4) +7 = 3x -12 +7

  f(g(x)) = 3x -5

— h(g(x))

  h(g(x)) = h(x -4) = (x -4)^2 +1 = x^2 -8x +16 +1

  h(g(x)) = x^2 -8x +17

definition: a circle is the  set of all points in a plane that are equidistant  from a given  point  called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to  any point  on the circle is a radius of the circle.
