1. DIRECTIONS: Find the value of f(x+h)-f(x)/h, h #0 for each of the following function.

1. f(x) = 4x +3
2. f(x) = x2 + 3
3. f(x)= x/2 -1
4.f(x) = X-1/2
5. f(x)=x²-1/2

Answer:

1. As you can see below line S is the only line that intercepts the y-axis at (0, -3). To ensure that line S represents the function f(x) = 4x - 3 we can take the slope. Again, as you can see the rise of this line is 4 and the run is 1 corresponding with the equation!

2. I assume that the function is f( x) = x^2 + 3, and the domain of f is all real numbers. Note that f(x) is a parabola opening upwards with a bottom at (0, 3). The function takes all positive values including 3 at x = 0. Hence the range is [3, +infinity).

3. f(x) = x2. This is its graph: Square function. f(x) = x2. It is a Parabola. It has symmetry about the y-axis (like a mirror image).

SORRY YAN LANG ALAM KO
