Answer 1

Plug in the respective values into the function. If each x gets mapped into 3*x + 4
Then
h(5)=15+4=19
h(4)= 12+ 4 = 16
h(-2) = -6 + 4 = -2
etc.

Answer 2

so i solve this ? h(-5)=15+4

Answer 3

i got - 19/5

Answer 4

so do i just put -19 as answer?

Answer 5

When a negative number is multiplied by a positive one, you get a negative product
-5*3 = -15

Answer 6

so i am suppose to multiply them by 3

Answer 7

h(x)=3x+4 is your function

That means that for every x you get, you plug in that number into every x variable in the function

h(1) = (3*1) + 4
h(2) = (3*2) + 4

Answer 8

then i simplify?

Answer 9

Exactly. You do the multiplication first and then add.

try again. What is the result of h(-5)?

Answer 10

so i solve for h or x

Answer 11

Remember that h is the function. Look at your problem:
h(x) = 3x+4
You can't solve for h really. All you can do is take the value and plug it back into the function they gave. since x = -5 this time, you plug -5 into all places x appears

Answer 12

5h/3 - 4/3

Answer 13

you're looking at h as a variable. It is a function. All it does is stand for what you're supposed to do.

h(x) means. h is the function name. x is the variable you're plugging things into

h(x) = \[x^{2}\] would take any number between the parentheses and square it

Answer 14

i just dont know

Answer 15

is this your first time seeing equations?

x is the variable. x is what you plug in to. h(-5) means you plug in -5 to the original equation

you get -5*3+4 = -15 + 4 = -11
There is no solving for h. That's your answer right there

Answer 16

i get it

Answer 17

so go through the x values and post your answer. I'll help you out with each step

Answer 18

-2*3+4

Answer 19

for the second?

Answer 20

exactly. and what does that evaluate to after simplifying it?

Answer 21

-2

Answer 22

yup, correct :D.
Go through the table and type out each value
