Question

Determine if the equation is linear,quadratic,exponential Y=x2-5*6

Answer 1

`y=x^2-5\cdot6`

Step 1

multiply 5 by 6

`\begin{gathered} y=x^2-5\cdot6 \\ y=x^2-30 \end{gathered}`

Step 2

watch the coefficient of x

`y=x^2-30`

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
