Question

Which graph represents the function f(x)=−4x−3?

Answer 1

the top left

Explanation:

just took the test

Answer 2

The graph on the top left.

Explanation:

f(x) =
`-4^x - 3`

That means that when x = 0...

f(0) =
`-4^0 - 3`

f(0) = -1 - 3

f(0) = -4

So, the function will have a point at (0, -4). We can eliminate the two graphs on the right.

When x = 1...

f(1) =
`-4^1 - 3`

f(1) = -4 - 3

f(1) = -7

So, the function will have a point at (1, -7). That corresponds to the graph on the top left.

Hope this helps!
