Julia is an intern at an architecture firm. she is given an assignment to create a bell-shaped structure that is symmetrical. she writes the function f(x)=3 squareroot -|x-2|+6 to model the structure. find the piecewise function that matches this absolute value function. then, graph the function using a graphing calculator and describe what you see.

The given function is

f(x)= 3 ⇒[Absolute value function]

F(x)=  1.  3 = when (x-2≥0→x≥2) ⇒[ Piecewise function]

   2. when [ x-2<0→x<2]⇒[ Piecewise function]

We see there is a shape which is is in the form of dome,point of intersection  of two curves being (2,7.348), symmetrical on both side of line x=2.

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
