Question

Y=x2-8x-3 standard to vertex form

Answer 1

Answer:

• y = (x - 4)² - 19

Step-by-step explanation:

Standard form of quadratic function:

• y = ax² + bx + c

Vertex form:

• y = (x - h)² + k

Convert the given function by completing a square:

y = x² - 8x - 3 =

     x² - 2*4*x + 4² - 4² - 3 =

    (x - 4)² - 19
