F(x)=-9x^2-2x and g(x)=3x^2+6x-9, find (f-g)(x) and (f-g)(-4)
Sergio039 [100]

Answer:

(f-g)(x) = -12x^{2} - 8x + 9

(f-g)(-4) = -151

Step-by-step explanation:

To find f-g(x) we subtract the common terms. So

f(x) = -9x^{2} - 2x

g(x) = 3x^{2} + 6x - 9

(f-g)(x)

(f-g)(x) = f(x) - g(x) = -9x^{2} - 2x - (3x^{2} + 6x - 9) = -9x^{2} - 2x - 3x^{2} - 6x + 9 = (-9 - 3)x^{2} + (-2 - 6)x + 9 = -12x^{2} - 8x + 9

(f-g)(-4)

(f-g)(x) = -12x^{2} - 8x + 9

We replace x by -4

(f-g)(-4) = -12(-4)^{2} - 8(4) + 9= -151

(f-g)(-4) = -151

What is the difference between 3x hdmi and 4x hdmi?
zzz [600]
There is a global standard for connecting high-definition electronics and PC products. HDMI technology helps in providing people with the highest signal possible to meet the current needs of HD entertainment systems with only a single cable that it uses for transmission. Currently, every new digital TV must have at least one HDMI port and the the connectivity has been standardized on one range of electronic products. 2x, 3x, 4x is the number of HDMI ports. This implies that 4x has more ports than 3x.
