Answer:
Answer:
Option C.
Step-by-step explanation:
The vertex form of a parabola is
where, a is constant, (h,k) is vertex.
If a<0, then it is a downward parabola and if a>0, then it is an upward parabola.
A downward parabola never lies entirely above the x-axis.
First equation is
It is a downward parabola and vertex is (-7,7).
Second equation is
It is an upward parabola and vertex is (7,-7).
Third equation is
It is an upward parabola and vertex is (7,7).
Fourth equation is
It is a linear equation with y-intercept -7.
Only equation 3 is an upward parabola whose vertex lies above the x-axis.
Answer:
you would have to solve for the x and y
Step-by-step explanation:
which means solve for the x then y
