Question

2. Calculate the y intercept of y = (x - 1)2 + 4

Answer 1

we have

`y=(x-1)^2+4`

Remember that the y-intercept is the value of y when the value of x is equal to zero

so

For x=0

substitute in the given equation

`\begin{gathered} y=(0-1)^2+4 \\ y=1+4 \\ y=5 \end{gathered}`

therefore

The y-intercept is the point (0,5)
