Q. Given the function f(x)=51x+56, then what is f(x−3) as a simplified polynomial?Answer:
Substitute x−3 into function: Substitute (x−3) into the function f(x). We have the function f(x)=51x+56. To find f(x−3), we replace every instance of x in the function with (x−3). f(x−3)=51(x−3)+56
Distribute (1/5) across terms: Distribute the (1/5) across the terms inside the parentheses.We need to multiply (1/5) by both x and −3.f(x−3)=(1/5)x−(1/5)×3+(6/5)
Simplify the expression: Simplify the expression.Now we simplify the multiplication and combine any like terms if possible.f(x−3)=51x−53+56
Combine constant terms: Combine the constant terms.We have two constant terms, −53 and 56, which we can add together.f(x−3)=51x+56−53f(x−3)=51x+53
