Concept:Find the image by substituting the given input value into the function rule.Explanation:The function is g:r→5−2r, so we can write g(r)=5−2r.We need the image of −3, which means we evaluate g(−3).Substitute r=−3 into the rule:g(−3)=5−2(−3).Simplify the bracket: −2(−3)=+6.So g(−3)=5+6.Hence, g(−3)=11.Answer:The image of −3 is 11, which is Option B.
