Can someone plz explain

4) x = 3/2 , x = -1/2

Steps:

(2x-1)² - 4 = 0

4x²-4x+1 - 4 = 0

4x²-4x-3 = 0

x = (4±√((-4)²-4×4×(-3))/2×4

x = (4±√(16+48)/8

x = (4±√(64)/8

x = (4±8)/8

x = 12/8 , x = -4/8

x = 3/2 , x = -1/2

1 and 2

step-by-step explanation:

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
