You can put this solution on YOUR website!
If f(x)=3x^2-7 and g(x)=2x+a, find a so that the graph crosses the y-axis at 68.
WHICH GRAPH?
IF YOU MEAN G(X) THEN
G(X)=2X+A.......WHEN IT CROSSES Y AXIS ...X=0 AND ..Y SHOULD BE 68..SO
68 =2*0+A
A=68
BUT WHY DID YOU GIVE
F(X)??DO YOU WANT GRAPH OF F(G(X))....OR.....G(F(X))?PUT QUESTION PROPERLY
