The table shows numbers with the ratio x : y? find the missing number?
x 1 15 225
y 4 ? 900

The value of missing number is:

60

Step-by-step explanation:

The ratio x:y is given below

x:y=1:4

x:y=15:?

x:y=225:900

The ratio x:y will remain same for every x and y

Hence, 1:4=15:?

Let a=?

a=60

Hence, the value of missing number is:

60

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
