We really need to see what you do know how to do, in order to be able to start. The first few questions are surely not that hard.Can someone assist me with this? I have no idea how to do it
To find the coordinate of the minimum point, look for the value that divides the graph into two equal halves.This is the graph for the first set of questions
I told you what to do for part (a); have you tried it? Evaluating f(-4) and f(2) should not be entirely new to you. And nasi112 has now demonstrated how to find f(-1), that is, to "plug -1" into the equation you were given.Well this is a complete new topic to me. We're supposed to use the text book to answer the questions but I do have a learning disability when it comes to numbers which means I need in person teaching or just with a person will be better but when I've learned something I don't forget it
For part (c), yes, the y-intercept is f(0); what did you get?I did try some of them. For A I was able to get (-4,6) and for D (2,6). For question c) I'm not 100% sure I did the right thing but I used 0 since x is 0 on the y axis. Question d I'm a bit lost as to how to start it.
For 4a) I was able to get-5, 4 & -5. The maximum point I got as 4 using 2 in 4 - (x-2)²
