Find the lateral area of the square pyramid.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
