Question

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

Answer 1

Answer:

The graph on the top left.

Step-by-step 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!
