Which function is the inverse of y = 1/4x^2 - 1, where x < 0

B

Step-by-step explanation:

25 x 25= 625

625-1= 624

B= y= -(200 + 1) which to the square root = 625

idk sry

step-by-step explanation:

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
