Find f(-2). 4 8 10 20

ICE Princess25 [194]

Answer:

The f(-2) is 20.

Step-by-step explanation:

f(x) = 2x^2 - 3x + 6

We have to find the f(-2),

f(-2) = 2×(-2)^2 - 3×(-2) + 6

f(-2) = 8 - (-6) + 6

f(-2) = 8 + 6 + 6

f(-2) = 20.

Answer:

The angle of DC is 130°.

Step-by-step explanation:

Given tha total angle in a centre(O) of circle, is 360. So in order to find ∠DOC, you have to subtract 85° and 145° from 360° :

∠COD = 360° - ∠COE - ∠DOE

= 360° - 85° - 145°

= 130°

For f(x) = 3x+ 1 and g(x) = x2 - 6, find (f+g)(x).

mylen [45]

Answer:

Step-by-step explanation:

$(f+g)(x)=f(x)+g(x)\\\\\text{Substitute}\ f(x)=3x+1,\ g(x)=x^2-6:\\\\(f+g)(x)=(3x+1)+(x^2-6)\qquad\text{combine like terms}\\\\(f+g)(x)=x^2+3x+(1-6)\\\\(f+g)(x)=x^2+3x-5$
