Which of the following properties could be used to rewrite the expression ( 2/3 x 1/5) x 5/2 as 2/3 x (5/2 x 1/5)? O The associative property followed by the commutative property
O The commutative property followed by the associative property
O The commutative property used twice
O The associative property used once

the answer is  

a.

4,624π mm2

step-by-step explanation:

(a) x intercepts: -6 and 2

you can obtain these by solving the equation 0=x^2 +4x-12 using your favorite quadratic formula. but it is easy to verify -6 and 2 indeed satisfy this equation.

(b) y intercept: -12

this is obtained by setting x=0: 0^2+4*0-12 = -12

(c) the minimum value is: -16 (this is the vertex)

you can get the vertex by rewriting the equation into the form:

there is no global or local maximum as the function goes to infinity, so only in the limit sense: +infinity.
