The graph of f(x) = 18x is reflected about the x-axis and shifted upward 8 units. what is the equation of the new function, g(x)? g(x) = state the y-intercept of g(x). (x, y) = state the domain and range of g( your answers using interval notation.) domain- range-

Reflecting a function across the x-axis changes every y-value to its opposite. That is, f(x) = 18x becomes g(x) = -18x.

Shifting a function upward 8 units adds 8 to every y-value. That is, g(x) becomes g(x)+8.

The combined effect of these two transformations on f(x) is to give you ...

... g(x) = -18x + 8

You recognize this as the equation of a line in slope-intercept form, with the y-intercept being +8. That is, g(0) = -18·0 +8 = 8. The y-intercept is ...

... (0, 8)

The domain and range of any linear equation is "all real numbers," that is, ...

... (-∞, ∞).

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
