F(x)=8x^2-2x+3 g(x)=12x^2+4x-3 what is h(x)=f(x)-g(x)?

Trava [24]

Answer: $h(x)=-4x^2-6x+6$

Step-by-step explanation:

To find the function h(x), you need to subtract the function $f(x)=8x^2-2x+3$ and the function $g(x)=12x^2+4x-3$ .

$h(x)=f(x)-g(x)\\h(x)=8x^2-2x+3-(12x^2+4x-3)$

Distribute the negative sign:

$h(x)=8x^2-2x+3-12x^2-4x+3$

Now you can add the like terms:

$h(x)=-4x^2-6x+6$

Therefore, you get that the function h(x) is:

$h(x)=-4x^2-6x+6$

which equation is the equation of the line in point slope form that has a slope of 12 and passes through the point (-1, 14)

Nostrana [21]

Point slope from would be 12x-y+26=0.

Black is the equation, 12x-y+26=0.

Orange is y-14=12(x+1)
Blue is y-14=12(x-1)
Red is y+14=12(x-1)
Green is y-14=-12(x+1)
