f (x) = xcubed + axsquared + bx + c.
If f(-3) = 0, f (4) = 0 and 4f (0) = 5f (1)
find the values of the constants a , b and c.
I've made 2 linear simultaneous equations from the f -3 = 0 and f 4 = 0
but for the 4f 0 = 5f 1 I dont know what to do.
Can anyone help me please?
they do work so what is being done with the similtaneous equations is where the trouble is
its not an easy one to do
your similtaneous equation shoul look like this
9a-3b+c = 27
16a+4b+c = -64
I put this into the SE on the TI89 and it returned your answers
still having ??
