Let f(x) = x + 2 and g(x) = x2. Find (gºf)(-5).

f(x) = x + 2

g(x) = x^2

(gºf) (-5) = g(f(-5))

(gºf) (-5) = (-5+2)^2

(gºf) (-5) = (-3)^2

(gºf) (-5) = 9

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
