[tex]\boxed{\boxed{f(x)=6(5)^x}}[/tex]
An exponential function is given by the following form:
[tex]y=ab^x \\ \\ Where: \\ \\ a \ is \ a \ constant \ and \ b \ is \ the \ base[/tex]
Here we know two points:
[tex](0,6) \ and \ (3,750)[/tex]
[tex]\bullet \ (0,6) \\ \\ x=0, \ y=6 \\ \\ 6=ab^0 \\ \\ \boxed{a=6} \\ \\\ \\ \bullet \ (3,750) \\ \\ x=3, \ y=750 \\ \\ 750=6b^3 \\ \\ b^3=\frac{750}{6} \\ \\ b=\sqrt[3]{125} \\ \\ \boxed{b=5}[/tex]
Finally, our exponential function is:
[tex]\boxed{\boxed{f(x)=6(5)^x}}[/tex]
