The &#8220;f&#8221; represents a function, which is a rule that assigns each input xx to exactly one output f(x)f(x).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The notation <strong>f(2)<\/strong> specifically asks, \u201cWhat is the value of the function f when the input is 2?\u201d After finding that value, you then multiply it by 3.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To solve this, you need to know the function\u2019s rule\u2014something like:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>f(x)=x+4f(x) = x + 4<\/li>\n\n\n\n<li>f(x)=3&#215;2\u22121f(x) = 3x^2 &#8211; 1<\/li>\n\n\n\n<li>Or any other formula.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For instance, if f(x)=x2f(x) = x^2, then: f(2)=22=4,so3f(2)=3\u00d74=12.f(2) = 2^2 = 4,\\quad \\text{so} \\quad 3f(2) = 3 \\times 4 = 12.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This process is a two-step operation:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Plug the input value (2) into the function to find f(2)f(2).<\/li>\n\n\n\n<li>Multiply the result by 3.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Without knowing what <strong>f(x)<\/strong> is, the value of <strong>f(2)<\/strong> is unknown. That makes <strong>3f(2)<\/strong> undefined in numeric terms until we get that information.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, <strong>you must be given a definition of the function f(x)<\/strong> in order to evaluate <strong>3f(2)<\/strong>. If it\u2019s not provided, you can only simplify it as <strong>3 \u00d7 f(2)<\/strong> and not compute a numerical answer.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Evaluate 3f(2) = . what does this equal The correct answer and explanation is: To evaluate 3f(2), we must understand the expression.
