A graph of 2 functions is shown below. graph of function f of x equals 2 multiplied by x plus 1 and graph of function g of x equals x cubed plus 2 multiplied by x squared minus x minus 2 Which of the following is an approximate solution for f(x) = g(x)? x = −2 x = 0 x = −1 x = 1
for the 2nd question i can't be sure how to write it Have you got a picture of the question?
yes :) (a graph ) hold on a sec let me get it
look at the graph The solution to f(x) = g(x) are where the graph intersect each other There is one of them which is equal to one of the options. Can you pick it out? Look at the 3 intersections and note the values of x.
they intersect at -1 on the x axis?
the graph not they
yes that's right x = -1 is the answer
its not exactly at x = -1 but very close . The question only asked for an approximate value.
yes but x=-1 is the only one that's in the choices.
ok perfect! could we do the other question now?
I don't understand it. It talks about functions but gives no details.
it asks what is true about the data ?
in the table are you sure you cannot help ?
the only thing I can see is for year 2012 f(x) = s(x) ( both are = to 732) so A
yea thats what it is.
ok i have 2 more and i did them i just want to make sure they are correct?
sorry I have to go now
