Q:
# Evaluate the function.a. f(x) = 3x+5 {-2,0,2}b. g(x) = x-9 find g(5)c. f(n) = (3-n) + 4 {-1,-2,3}

Accepted Solution

A:

Answer:Part a) The values of the function f(x) are {-1,5,11}Part b) The value of g(5) is -4Part c) The values of the function f(n) are {8,9,4}Step-by-step explanation:Part a) we havef(x)=3x+5Evaluate for {-2,0,2}1) For x=-2substitute the value of x in the functionf(-2)=3(-2)+5=-12) For x=0substitute the value of x in the functionf(0)=3(0)+5=53) For x=2substitute the value of x in the functionf(2)=3(2)+5=11Part b) we haveg(x)=x-9Evaluate for x=5substitute the value of x in the functiong(5)=5-9=-4Part c) we havef(n)=(3-n)+4Evaluate for {-1,-2,3}1) For n=-1substitute the value of n in the functionf(-1)=(3-(-1))+4=82) For n=-2substitute the value of n in the functionf(-2)=(3-(-2))+4=93) For n=3substitute the value of n in the functionf(3)=(3-(3))+4=4
