Answer:

Step-by-step explanation:
So we have the function:

And we want to find g(0).
To do so, substitute 0 into x:

Multiply:

So, the value of g(0) is -2.
And we're done!
Yes because it goes up and back down
You can use the equation to find the slope of a line given two points. This equation is y2 - y1 divided by x2 minus x1. The y2 is represented by the y coordinate of the second ordered pair, but it really doesn't matter, either way you get the same answer. The same way the x2 is represented by the x coordinate of the second ordered pair. For this problem, I will just use the normal coordinates. So the second y coordinate is 3. 3 -0 = 3. So your numerator is 3. The second x coordinate is 2. 2-0 = 2. So the denominator is 2. This is 3/2. So your slope would be 3/2. Hope this helps. :D Let me know if you didn't understand something in my explanation.
Answer: the last one
Step-by-step explanation: because 7 times 24 equals 168 and x would be 21 so 21 times 8 equals 168.
