Question

If f(x) = x - 4, what does f(3) represent?

The value of (x - 4) when x = 3

The value if x when (x - 4) = 3

The value of 3f(x) when x = 3

The value of f(x) when (x - 4) = 3

Answer 1

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

The value of (x - 4) when x = 3.....I think

Answer 2

I have a similar question to this could you help me on that too?

Answer 3

I am not the best at functions...but I can look at it and see

Answer 4

Choose the equation below that represents the line passing through the point (2, -5) with a slope of -3.

y = -3x - 13

y = -3x + 11

y = -3x + 13

y = -3x + 1

Answer 5

y = mx + b
slope(m) = -3
(2,-5)..x = 2 and y = -5
now we sub...and since we know m, the slope, we need to find b, the y intercept
-5 = -3(2) + b
-5 = -6 + b
-5 + 6 = b
1 = b
so our equation is : y = -3x + 1

Answer 6

I would stay longer and help more, but there is somewhere I have to be in a little bit. I will be back on later.
