Given f(x) = 10 -2xfind f(7). –4 3 7 56

Accepted Solution

Answer: [tex]f(7)=-4[/tex]Step-by-step explanation: 1. You have the following function given in  the problem: [tex]f(x)=10-2x[/tex] 2. Then, to find [tex]f(7)[/tex] asked in the exercise, you only need to substitute [tex]x=7[/tex] (which is the input value) into the given function. 3. Therefore, keeping the above on mind, you obtain that [tex]f(7)[/tex] is: [tex]x=7[/tex] [tex]f(7)=10-2(7)[/tex] [tex]f(7)=10-14[/tex] [tex]f(7)=-4[/tex]
