Question

Write the equation for the quadratic function in the graph

Answer 1

Answer:

${x}^{2} - 16 = 0 \: is \: the \: equation$

Step-by-step explanation:

$x = - 4 \\ or \: x = 4$

$(x + 4) = 0 \: or \: (x - 4) = 0 \\ (x + 4)(x - 4) = 0 \\ open \: the \: bracket$

$x(x - 4) + 4(x - 4) = 0$

${x}^{2} - 4x + 4x - 16 = 0 \\ {x}^{2} - 16 = 0$
