The left side can be written as a square. We can take the square root, then subtract 1.

... (x +1)² = 17

... x +1 = ±√17

... x = -1 ±√17

Question 1 (1 point)<br> Which equation can be represented by a graph with a vertex at (1,3)?

madam [21]

Answer:

See explanation

Step-by-step explanation:

You have not provided the options to help us give you a specific answer.

If a quadratic function is written in the form

$f(x) = a {(x - h)}^{2} + k$

Then (h,k) is the vertex, and 'a' is a constant.

For instance

$f(x) = 5 {(x - 1)}^{2} + 3$

has vertex at (2,3).

Also, an absolute function in the form

$g(x) = a |x - h| + k$

has vertex at (h,k).

This means

$g(x) = |x - 1| + 3$

also has vertex at (1,3).

I hope this explanation is helpful.
