For the function ƒ(x) = x2 – 4, find the value of ƒ(x) when x = 6.

f(x)= 2x -4

when x=6

f(x) = 2(6)-4

=12-4

=8

8

Step-by-step explanation:They said f(x)=x2–4 and they said find the value of f(x) when x=6

When x=6 you equate the value of x into the question

F(6)=6*2–4=8

Therefore the value of f(x) is 8

do you have any choices

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
