Enter the letter for the function graphed below. <br> A) y=3^sqrt x-3<br> B) y=3 sqrt x -3

Ira Lisetskai [31]

Answer: е) Step-by-step explanation: we know the coordinates of the points so we can easily determine which function this is To begin with, let's take any two points with an integer coordinates let these be two points with coordinates (1 ; 4) and (0 ; 3) Now let's check $a) \ \displaystyle\bf 4=\sqrt[3]{1-3} \ \ wrong$ and all other options except option e are incorrect because $\displaystyle\ e) \sqrt[3]{1} +3=4 \ \ right$

Which trinomial is the product of the expression below ? (2R-3) (R+12)

anastassius [24]

Answer:
2R^2 + 21R - 36

Explanation:
To answer this question, we will follow these steps:
1- expand the brackets
2- gather like terms

Steps are as follows:
(2R-3)(R+12) = 2R(R) + 2R(12) - 3(R) - 3(12)
= 2R^2 + 24R - 3R - 36
= 2R^2 + 21R - 36

Hope this helps :)
