Could somone please provide some pointers on how to tackle these
sorts of questions. I find them a bit scary. the graph given is
the x-intercepts give the x-values for which y = 0 so for this
graph, the x-intercepts are the x-values such that: or in other
words, where so the solutions to the first question is simply
the x-intercepts, which you can tell by looking on the graph For
the second question: we want the solutions to this is where So
draw the line , the x-values of the points of intersection are
your solutions in the following problem we were asked to draw a
line to find solutions to the equation , but i know nothing
about that equation from the graph, all i know about from the
graph is the equation , so i have to somehow create this graph
from the new graph given so i can get the required
intersections. so we begin with the new graph given: (remember,
my objective is to extrapolate from this graph since i need a +x
i have to add 2 x's to -x, but since this is an equation, i have
to add it to both sid
