the domain of f(x)= x2 +1 is limited to {0,1,2,3)
the maximum value will be at the maximum value of x which is at x = 3
So, the maximum value of the range will be = 3^2 + 1 = 9 + 1 = 10
80 is the old value and 86 is the new value so I thin the change was only 6% sorry if this is wrong
Answer:
(-1, 3) and (1, 5).
Step-by-step explanation:
Remember that graphically, the solutions for a system of equations are all the points where the graphs intersect.
In the graph of the system of equations, we see that the they intersect once at (-1, 3) and again at (1, 5).
Therefore, our two solutions to the system are (-1, 3) and (1, 5).
One polynomial identity that crops up often in various areas is the difference of squares identity:
A2-b2=(a-b) (a+b)
We meet this in the context of rationalising denominators.
