Solution
Find the y-intercept for following equation:
[tex]f(x)=-(x+1)^2[/tex]Using the slope equation formular:
[tex]\begin{gathered} y=mx+c \\ f(x)=-(x+1)^2 \\ f(x)=-x^2-2x-1 \end{gathered}[/tex]The value of y when x = 0
[tex]\begin{gathered} f(0)=-0^2-2(0)-1 \\ y=-1 \end{gathered}[/tex]Hence the answer is - 1
