Question 2 Multiple Choice Worth 1 points)

likoan [24]

Answer:

Solution: means we replace 'x' with 'x+1' and we get g (x). Let us put x = 0 and then y = 0 to find two points on coordinate axis to easily plot the graph of g (x). Now, let us put y = 0 and find out x. So, second point is . Now, let us plot A and B then extend the line joining AB.

Please break this up:<br> a^2-b^2-4b-4

hoa [83]

(a + b) (a-b ) - 4b - 4

<u>Explanation:</u>

Given:

a² - b² - 4b - 4

(a + b) (a-b ) - 4b - 4

This equation cannot be solved further.

Thus, the equation is (a + b) (a-b ) - 4b - 4
