Complete the square to transform the expression x2 + 4x + 2 into the form a(x − h)2 + k. (x + 2)2 − 2 (x + 2)2 + 2 (x + 4)2 − 2 (x + 4)2 + 2

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
