Answer:
Step-by-step explanation:
(x - h) {}^{2} + (y - k) {}^{2} = {r}^{2}(x−h)
2
+(y−k)
2
=r
2
here
r = 7. (the circle is symmetrical with y - axis )
h = 0. and k = 1
Thus equation of circle is,
(x - 0) {}^{2} + (y - ( - 1)) {}^{2} = {7}^{2}(x−0)
2
+(y−(−1))
2
=7
2
x^2 + (y+1)^2 = 49
Answer:

Answer:
A and C.
Step-by-step explanation:
It says that the a value increases by 2 but that still doesn't change the fact the graph is infinite. So the domain is still the same, and the range is still the same.
<span>hello :
اthe vertex of the absolute value function defined by ƒ(x) = |x + 5| + 7 is :
</span>(-5,7) because when : x= - 5 ...f(-5) = |- 5 + 5| + 7 = 0+ 7 = 7
