If f(x) = x − 8, what is 3f(x)?यदि f(x) = x − 8 है, तो 3f(x) क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 3x − 243x − 24
The expression 3f(x) means 3 times the entire function value. Substituting f(x) = x − 8 gives 3f(x) = 3(x − 8) = 3x − 24, so option C is correct.3f(x) का अर्थ है फलन के पूरे मान को 3 से गुणा करना। f(x) = x − 8 रखने पर 3f(x) = 3(x − 8) = 3x − 24 मिलता है, इसलिए विकल्प C सही है।
