If f(x) =x^2 -2 and g(x) = 4f(x)-1 then what is the value of g(-3)?

g(x) = 4f(x)-1

g(x) = 4(x^2-2) -1

g(3) = 4(3^2-2) -1

      = 4(9-2) -1

      =4*7 -1

 = 28-1

=27

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
