Please solve part 4:
(iv)
Dear Student,
The answer to part (i) is given below:
|x^2 - 7x + 10|
finding the zeroes of the equation, we have:
x^2 - 7x + 10 = 0
or, x^2 - 2x - 5x + 10 = 0
or, x(x-2) -5(x-2) = 0
or, (x - 2)(x - 5) = 0
Therefore, at x = 2 and x = 5, the equation intercepts x axis, and the value is negative in between 2 and 5.
Therefore, the equation should be represented as,
x^2 - 7x + 10 for x<2
x^2 -7x +10 for x>5
For the remaining queries, please repost the question for instant advice from our experts.
I hope you understood the solution
