The graph of f(x) = 10x is reflected about the x-axis and shifted upward 7 units. What is the equation of the new function, g(x)? State its y-intercept, domain, and range.
Consider the parent graph;
f(x) = 10x
Consider the graph is reflected about the-axis, then;
-g(x) = -10x
The graph is shifted upward by 7 units, then, the new function for the parent graph is;
g(x) = -10x + 7.
The characteristic of the graph of the parent graph in form f(x) = bx, is written as follows:
The parent graph g(x) = -10x + 7 is;
1. One-to-one function.
2. Horizontal asymptote is y = 0.
3. Domain of the graph is set of all real numbers, that is (-∞, ∞).
4. Range is set of all real numbers lesser than 7.
To find the y-intercept set x = 0, as follows:
y = -100 + 7
= -1 + 7
= 6
Therefore, y-intercept is (0, 6).
Therefore, y-intercept is (0, 6).
