Which statement best describes how to determine whether f(x) = x2 – X + 8 is an even function? Determine whether thy-(-x) + 8 is equivalent to x2 – X + 8.
Determine whether (-x)2 – (-x) + 8 is equivalent to x2 – X + 8.
Determine whether x2 - (-x) + 8 is equivalent to -(x2 – X + 8).
Determine whether (-x)2 – (-x) + 8 is equivalent to -(x2 - - X + 8).

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

answer: 72: 111

step-by-step explanation:

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
