Part 1) f(6)=30

Part 2) f(4)=27

Part 3) g(-2)=6

Part 4) Part 5) Part 6) and part 7) in the procedure

Step-by-step explanation:

Part 1) we have

f(x)=2.50x+15

we know that

f(6) is the value of the function when x=6

so

substitute the value of x in the function

f(6)=2.50(6)+15=30

Part 2) we have

f(x)=42-3.75x

we know that

f(4) is the value of the function when x=4

so

substitute the value of x in the function

f(4)=42-3.75(4)=27

Part 3) we have

g(x)=5x+16

we know that

g(-2) is the value of the function when x=-2

so

substitute the value of x in the function

g(-2)=5(-2)+16=6

Part 4) Which of the following functions match these outcomes:

f(1)=6

we know that

f(1) is the value of the function when x=1

so

substitute the value of x in each of the functions and then compare

f(1)=5(1)+1=6 -----> this function matches the outcome

f(1)=4(1)+2=6 -----> this function matches the outcome

$f(1)=(1)^{2}+4 =5$ -----> this function does not match the outcome

f(1)=2(1)+4=6 -----> this function matches the outcome

f(1)=12-2(1)=10 -----> this function does not match the outcome

Part 5) Which of the following functions match these outcomes:

f(2)=8

we know that

f(2) is the value of the function when x=2

so

substitute the value of x in each of the functions and then compare

f(2)=5(2)+1=11 -----> this function does not match the outcome

f(2)=4(2)+2=10 -----> this function does not match the outcome

$f(2)=(2)^{2}+4 =8$ -----> this function matches the outcome

f(2)=2(2)+4=8 -----> this function matches the outcome

f(2)=12-2(2)=6 -----> this function does not match the outcome

Part 6) Which of the following functions match these outcomes:

f(3)=10

we know that

f(3) is the value of the function when x=3

so

substitute the value of x in each of the functions and then compare

f(3)=5(3)+1=16 -----> this function does not match the outcome

f(3)=4(3)+2=14 -----> this function does not match the outcome

$f(3)=(3)^{2}+4 =13$ -----> this function does not match the outcome

f(3)=2(3)+4=10 -----> this function matches the outcome

f(3)=12-2(3)=6 -----> this function does not match the outcome

Part 7) Which of the following functions match these outcomes:

f(4)=12

we know that

f(4) is the value of the function when x=4

so

substitute the value of x in each of the functions and then compare

f(4)=5(4)+1=21 -----> this function does not match the outcome

f(4)=4(4)+2=18 -----> this function does not match the outcome

$f(4)=(4)^{2}+4 =20$ -----> this function does not match the outcome

f(4)=2(4)+4=12 -----> this function matches the outcome

f(4)=12-2(4)=4 -----> this function does not match the outcome
