f[x_] := -x^2 + 6 x;
g[a_, x_] := a*x;
Plot[{f[x], Table[g[a, x], {a, 0, 3}]}, {x, 0, 7}, Frame -> True,
Axes -> False]
Plot3D[{f[x], g[a, x]}, {x, 0, 7}, {a, 0, 3}]

=============
Is there a way to do a Plot do draw this two functions in the same graph ?
I am asking because i am having problems due the parameter "a".
I have,
f(x)= -x^2 + 6x
g(x)= ax
i want to draw them in the same graphic and with a from 0 to 3 . . .
Can not think of a way of doing this, due the "a" parameter . . .
Plot[{f[x],[g[a][x]},{x,0,7},{a,0,3}]
Can some help me out with this small issue ?
In Latex,
\text{Clear}[x,f,g]
f[\text{x$\_$}]\text{:=}-x^2+6x
\text{Nullstellen} \text{von} f[x]
\text{Solve}[f[x]==0,x]
\{\{x\to 0\},\{x\to 6\}\}
\text{Fl{\" a}che} \text{von} f[x]
\int_0^6 f[x] \, dx
36
\text{Clear}[x]
g[\text{a$\_$}][\text{x$\_$}]\text{:=}a*x
\text{Graphisch} \text{dargestellt}
\text{Plot}[f[x],\{x,-0.2,6.2\}]
\text{Plot}[\text{Table}[g[a][x],\{a,0,3\}],\{x,0,2\}]
