Which function has the given properties below? the domain is the set of all real numbers. one x-intercept is(2pi,0) the amplitude is 4.
the point (pi/2,-4) is on the graph.
the y-intercept is (0, 0)

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.

i suppose it should be (y=2x-5)

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)

step-by-step explanation:
