F(x) = 2x2 – 4x – 30 = 2x2 – 4x – 33 = 2(x2 – 2x)3 + 1 = 2(x2 – 2x + 1)4 = 2(x – 1)22 = (x – 1)2± = x – 11 ± = x mica is solving for the zeros of a quadratic function by completing the square. her work is shown. what error did mica make?

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
