Answer:

Step-by-step explanation:

a) -2g

putting the value of g

-2 $(\frac{3}{-1} )$

opening the brackets by multiplying

= $(\frac{-6}{1})$ =-2g

b)f+3g

= $\frac{-2}{4}+\frac{9}{-3}$

taking LCM AS 12

= $\frac{-2*3}{4*3} +\frac{9*4}{-3*4}$

=-6/12-36/12

=-42/12

=-7/2

c)2f-4g

= $2(\frac{-2}{4})-4(\frac{3}{-1} )$

= $\frac{-4}{4}-\frac{12}{-1}$

=-1+12

=11

Match the following key attributes for the graph

anzhelika [568]

Answer:

Domain: [-4, ∞]

Range: [-6, ∞]

Step-by-step explanation:

The domain is the set of the possible x values

The range is the set of the possible y values.

In the graph, we can see that the function cuts in a given part. We can see that for the x-values, the smallest one is x = -4, and then the function extends to the right (we see no limit at the right, then there is none)

This means that the domain is:

D: [-4, ∞]

For the y-values, the smallest value is when x = -4, and the y-value is -6

Then we can see that, as x increases, the same happens for y.

Then the range is:

R: [-6, ∞]
