Question

Consider the function f(x)=−23x+5 . What is f(12) ? Enter your answer, as a simplified fraction, in the line. f(1/2)=___

Answer 1

-33/2 improper for f(1/2) but for f(12) it is
$23 \times 12 + 5$
so 276 plus 5 equals 281 but that is for f(12) I do not know bf you meant f(1/2) or f(12) but here are not the answers (:

Answer 2

Function: f(x) = -$\frac{2}{3}$x + 5.

Answer: f($\frac{1}{2}$) = $\frac{14}{3}$
