Answer:
3x²+2x+4
Step-by-step explanation:
using the foil distributive method
To prove a rhombus you need to show that the sides are congruent and the diagonals are perpendicular.
Sides:
≅ ≅ ≅
Diagonals:
Use the slope formula:
= -1
= 1
Slopes are opposite reciprocals so they are perpendicular.
***************************************************************************
All of the sides are congruent and the diagonals are perpendicular so RMBS is a rhombus.
I think it’s 92% not to sure tho
The domain is related to the x-value of the function. In this case, the goal of finding the domain is to make sure that the number under the radical sign is positive. The number that makes the function under the radical sign is -2. Hence this is the minimum number and the domain is from -2 to positive infinity.
