Week 4 tutorial question 6.b

[Anwesha Ghosh]

In the following question:

Consider the function f1 = −x^2 + 8x + 6. Two points P and Q are on the resulting

parabola such that they are two units away from the axis of symmetry. If V represents

the vertex of the curve, answer the following.

(b) Consider another curve representing function f2 such that f2 = (x − 4)^2. Now let

A be the set of all points inside the region bounded by these curves (including the

curves), what is the range of y − coordinate of the points in A ?

Is there anyway we could find the range of x − coordinate of the points in A ?

Thanks!

Dear learner,

 Solving the questions by drawing a figure is a good way without missing anything which explained in the video. Otherwise, you can take the intersection  of the domains and range of both the functions for x- coordinate  and y- coordinate respectively of the points in A
