Answer:
The answer is 7/6x - 75.
Step-by-step explanation:
17 - 1/5x +2/3x - 92 + 7/10x
17 - 6/30x + 20/30x - 92 + 21/30x
-6/30x + 20/30x + 21/30x = 35/30x or 7/6x
17 - 92 = -75
7/6x - 75
A parabola is a mirror-symmetrical U-shape.
- The equation of the parabola is
- The focus is
- The directrix is
- The axis of the symmetry of parabola is:
From the question, we have:
The equation of a parabola is:
Substitute the values of origin and vertex in
Collect like terms
Solve for a
Substitute the values of a and the vertex in
The focus of a parabola is:
Substitute the values of a and the vertex in
The equation of the directrix is:
So, we have:
----- the directrix
The axis of symmetry is:
We have:
Expand
Expand
A quadratic function is represented as:
So, we have:
Recall that:
So, we have:
This gives
Hence, the axis of the symmetry of parabola is:
