Question1: is the equation of the symmetry with respect to y axis of ,find m
Question2: If f:RtoR and are given. Find the area of the triangle which is bounded by the symmetry axis of ,the line and the axis. Thanks in advance for the solution of these questions.
There are a number of ways of showing thatOriginally Posted by JohnDoe
the symmetry axis is the vertical line .
Each way finds the x-coordinate of the turning point of the given parabola.
The area of a triangle is .
A simple sketch graph shows that:
The base of the triangle is .
The height of the triangle is .
You need magnitudes because can be positive or negative depending on the value of k ......
