42. Error Analysis Describe and correct the error made in factoring
9x2 squared - 49=(9x + 7) (9x - 7)

(3x + 7)(3x - 7)

Step-by-step explanation:

9x² - 49 ← is a difference of squares and factors in general as

a² - b² = (a + b)(a - b) , then

9x² - 49

= (3x)² - 7²

This is where the error has been made in that 9x has been used instead of 3x

= (3x + 7)(3x - 7) ← in factored form

i would say c is the best answer, hope it's right!

good luck! =)

cutie~

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
