Write the following function in standard form. show your work. y=(x-5)(x+5)(2x-1)

Step-by-step explanation:

The given function is

Observe that, the first two factors are from difference of two squares.

We expand the brackets using the distributive property to obtain;

The above function is now in standard form, since the terms are arranged in descending powers of .

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)
