Which graph represents the function f(x)=−4x−3?
Evgen [1.6K]
<h2>Answer:</h2>

The graph on the top left.

<h2>Step-by-step explanation:</h2>

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.
