So, since we know what is y= to. we are going to plug in that equation for y I n the 2nd equation.
for example:
y=3/4x+5
4x-3(3/4x+5)= -1
4x-9/4x+15=-1
16/4x-9/4x=-16
5/4x=-16
multiply by the reciprocal on both sides toget x.
4/5(5/4x)= (-16)4/5
x= -64/5 = -12 and 4/5ths
First of all, we need to know what is the vertex means which is the maximum or minimum point of a parabola and the formula will be:
x=-b/2a
Where b and a from
f(x)=ax^2+bx+c
So do find which function has a vertex of origin. Let's find the vertex of all the function that we had:
f(x)=(x+4)^2
f(x)=(x+4)(x+4)
f(x)=x^2+8x+16
x=-b/2a
x=-8/2(1)
x=-8/2
x=-4
Not the right answer because the vertex needs to be origin which is x=0
f(x)=x(x-4)
f(x)=x^2-4x
x=-b/2a
x=-(-4)/2(2)
x=4/4
x=1
Not the right answer
f(x)=(x-4)(x+4)
f(x)=x^2-16
x=-0/2(1)
x=0
Yay! This is the right answer. As a result, f(x)=(x-4)(x+4) is your final answer. Hope it help!
