Answer:
a four sided parallelogram where all angles are the same and all sides are the same length
Answer:
x = ±1
Step-by-step explanation:
We have to assume you want the solution for y = 0:
0 = x² -1
1 = x² . . . . . . add 1
±1 = x . . . . . . take the square root
x = ±1
Answer:
The domain is
and its range is 
The y-intercept is (0,3).
Step-by-step explanation:
Consider the parent function
Its domain is
and its range is 
The graph of the function
is obtained from the graph of parent function by translation 3 units up (see diagram). This translation doesn't change the domain and will change the range of the function, thus the domain is
and its range is 
To find th y-intercept you have to find y at x=0:

Hence, the y-intercept is (0,3).
Y=4x+7
So 4 is the rate of change because if you solve for y, x is the rate of change
