f(x)= e^(3x+1) -2

the curve y=f(x) meets the y-axis at the point P and the x-axis at the point Q

find the exact coordinates of P and Q

ive tried to work out P and Q by taking x=0 and y=0 respectively is this right? it just doesnt seem like much working out for the amount of marks it's worth. can someone please show me their working for this question?
