Tell whether the function is linear. Then evaluate the function when x=-6 times f(x) = 3x + 4 1. Not linear: -14
2. Linear: -14
3. Linear: 14
4. Not linear: -14

F(-6)=-14 not linear!

Aquadratic function is one of the form f(x)=ax2 + bx + c l, where a,b, and c are numbers with are not equal to zero.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
