Hi, today we are solving the question in which fx is equals to minus 3 plus 6x plus 4 and fx is equals to x minus 2.
00:15
So equating both the function first we get minus 3 plus 6x plus 4 is equals to x minus 2.
00:29
So here we get 1 6x plus 1 is equals to x minus 2.
00:40
So here 6x minus x is equals to minus 2 minus 1.
00:45
So we get it here as 5x is equals to minus 3.
00:52
So x will be equal to minus 3 by 5.
01:12
Now finding the y coordinate of the intersection point.
01:17
So plugging the value of x in the y function.
01:24
So here intersection point will be given by f of 1 by of minus 3 by 5 is equals to minus 3 by 5 minus 2.
01:39
So we get minus 3 minus 10 by 5.
01:42
So we get minus 13 by 5.
01:46
So we get the coordinate point as x or y is equals to minus 3 by 5 or minus 13 by 5.
01:59
Now finding the vertex of the parabola.
02:02
The vertex of the parabola in the form fx is equals to ax square plus bx plus c is given by the form x is equals to minus b by 2a.
02:21
So here a is equals to a is equals to 6 and b is equals to 4...
