Question

Choose the correct answer for each of the following questions Find the y-intercept for following equation F(X)=-(X+1)^21- -12- -13-X4-0

Answer 1

Find the y-intercept for following equation:

`f(x)=-(x+1)^2`

Using the slope equation formular:

`\begin{gathered} y=mx+c \\ f(x)=-(x+1)^2 \\ f(x)=-x^2-2x-1 \end{gathered}`

The value of y when x = 0

`\begin{gathered} f(0)=-0^2-2(0)-1 \\ y=-1 \end{gathered}`

Hence the answer is - 1
