Answer quick
1. given the function f(x) = 3x + 4.

determine the value of f(x) when x = -1.
question 5 options:

f(−1) = −2

f(−1)= −1

f(−1) = 1

f(−1) = 0

2. if f(x) = −3x + 8, , find f(5).
question 8 options:
5
-7
7
-5

3. if g(x)= 3/4x +2,find g(−12).
question 10 options:

g(-12) = x
g(-12) = 3/4
g(-12) = 2
g(-12) = -7

1. f(-1)=1, 2.f(5)=-7, 3.g(x)=-7

Step-by-step explanation:

Hello

a function f(x)= y means that y is the dependent variable and  x is the independent variable, (the value of y depends on x)

in this case, all you have to do is put the values into the equation

Step 1

1.

f(x) = 3x + 4

x=-1

f(-1)=3(-1)+4

f(-1)=-3+4

f(-1)=1

Step 2

2.

f(x) = -3x + 8

x=5

f(5)=-3(5)+8

f(5)=-15+8

f(5)=-7

Step 3

g(x)=(3x/4)+2

g(-12)=((3*-12)/4)+2

g(-12)=(-36/4)+2

g(-12)=-9+2

g(-12)=-7

g(-12)=-7

Have a great day
