Hey guys, i have two questions, first, how do you identify the axis of symmetry for a function given the vortex? so for example, vertext: (1/2, -3) and lastly, how does one identify a function as linear, quadratic, or neither? for example, f(x)=-x^2

they are simplified

step-by-step explanation:

answer: check all that apply, where the options?

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
