Question

function question: Given h(x)=5, find:
a. h(2)
b. h(x+3)
c. h(-x)

Answer 1

Do you know where to start with this?

Answer 2

No

Answer 3

so for a function, like f(x)=x, if it's f(1)=1, you just replace the x with your number. In this case, you may be overthinking it.

Answer 4

How am I overthinking it?

Answer 5

how can you solve h(2) if there is nothing to plug in? I'm just really confused

Answer 6

Right, so what does the function tell you? No matter what you plug in for x, the answer will be 5.

Answer 7

So the answer is h(2)=5?

Answer 8

Yep!

Answer 9

Okay thank you, so the second one is just h(2+3)=5?

Answer 10

Also I'm a bit confused why h(2) would equal five, like logically speaking. I understand the concept but still.

Answer 11

If you graph the function, it would be a horizontal line at y=5, so no matter what x equals, the answer will always be five.

Answer 12

That makes sense, thank you!

Answer 13

would the second one be h(2+3)=5 and the third one h(-5)=5?

Answer 14

Examples to clarify:
if h(x)=5+x, then h(1)= 5 +1 and h(1)=6

if h(x)=5x, then h(1)= 5(1) and h(1)=5

if h(x)=5, then h(1)= 5, and h(1)=5

Answer 15

Thank you this is easier to understand.
