Distribute 6 to terms: We are given the function c(n)=−7+6(n−1). The first step is to distribute the 6 to both terms inside the parentheses.Calculation: c(n)=−7+6×n−6×1
Combine like terms: Now, we simplify the expression by combining like terms.Calculation: c(n)=−7+6n−6
Combine constant terms: Combine the constant terms −7 and −6 to get a single constant.Calculation: c(n)=6n−13
