Given f(x)= 2x²+4x-6 and g(x)=2x-2, find each function
valkas [14]
F(x)= 2x²+4x-6 and g(x)=2x-2, find each function
1. (f/g) (x) = f(x)÷g(x) = (2x²+4x-6)÷(2x-2)
First factor both top and bottom:
(2x-2)(x+3)÷(2x-2) = x+3

2. f(a + 2) = plug (a+2) in anywhere there is an x in f(x)=2x²+4x-6 -->
2(a+2)^2 +4(a+2)-6 = 2(a^2+4a+4)+4a+8-6, now distribute:
2a^2+8a+8+4a+2, combine like terms
2a^2+12a+10

3. g(a/2) = plug (a/2) in anywhere there's an x in g(x)=2x-2:
2(a/2)-2 = a-2

Are these correct? ILL MARK YOU BRAINLIEST
Oxana [17]

Answer:

Yes

Step-by-step explanation:

1) Cos 300 = Cos (360 - 60) = Cos 60    {Cos 360 - theta = Cos theta}

                                              = 1/2

Sin 300 = Sin (360 - 60) = -Sin 60 = \frac{-\sqrt{3}}{2}

3) 3π/4 = 3*180/4 = 135

Cos 135 = Cos (90 + 45) = -Cos 45 = \frac{-\sqrt{2}}{2}

Sin 135 = Sin (90 + 45) = Sin 45 = \frac{\sqrt{2}}{2}
