Respuesta :

[tex]y=x^2-5\cdot6[/tex]

Step 1

multiply 5 by 6

[tex]\begin{gathered} y=x^2-5\cdot6 \\ y=x^2-30 \end{gathered}[/tex]

Step 2

watch the coefficient of x

[tex]y=x^2-30[/tex]

it is 2,

remember

if the coefficient is 1 is a linear function

if the coefficient is is 2 is a quadratic function

if coefficient is 2 or more, it is an exponential function

then

the function is quadratic
