What is the range of y =|3x + 1|?

Question 17 options:

a)

{y|y≥0}

b)

{y|y≥1}

c)

{y ∣∣ y≥13}

d)

{all real numbers}

Y | Y > 0

Step-by-step explanation:

The absolute value expression has a v shape. The range of a positive absolute value expression starts at its vertex and extends to infinity

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
