The value of c is 
Explanation:
Given that the trinomial is 
We need to determine the value of c such that the trinomial is a perfect square.
The value of c can be determined using the formula,
From the trinomial, the value of b is given by
Substituting the value of b in the above formula, we have,
Squaring both the numerator and denominator, we have,
Thus, the value of c is which makes the trinomial a perfect square.
Answer:
x^2 + y^2 = 49
Step-by-step explanation:
For center (h,k) and radius r, eqution of the respective circle is
(x-h)^2 + (y-k)^2 = r^2
x< -1 is the graph going down or up when x is less than -1? its going down , so this is true
Range is the y values. It appears to go down to y=5 and go up so its not all reals
x< -1 is the graph going down or up when x is less than -1? its going down , so this isn't true
Domain is the x values and it does include all reals
Minimum (-1, 5), is that the value of vertex at the bottom, yes it is, so this is true
