If f(x) = |x| and g(x) = x, what is the value of (f + g)(-4)?यदि f(x) = |x| और g(x) = x हों, तो (f + g)(-4) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 00
The sum of functions is defined by (f + g)(x) = f(x) + g(x). At x = -4, f(-4) = |-4| = 4 and g(-4) = -4, so (f + g)(-4) = 4 + (-4) = 0.फलनों का योग (f + g)(x) = f(x) + g(x) से परिभाषित होता है। x = -4 पर f(-4) = |-4| = 4 और g(-4) = -4, इसलिए (f + g)(-4) = 4 + (-4) = 0।
