The parent function is given to be:


f(x)=10^x

The new function is given to be:


g(x)=-4f(x)+12

Therefore, the function will be:


g(x)=-4(10)^x+12

The y-intercept is the value of y when x = 0. Therefore, we have:


\begin{gathered} y=-4(10)^0+12 \\ y=-4+12 \\ y=8 \end{gathered}

Therefore, the y-intercept is:


\mathrm{Y\:Intercepts}:\:\left(0,\:8\right)
