Answer:
The domain of h(x) is {x : x ∈ R}
The range of the function is {y : y > -9}
The horizontal asymptote is at y = -9
Step-by-step explanation:
* Lets read the problem and solve it
- The exponential function is f(x) = a(b)^x, where a and b are constant
and b is the base , x is the exponent , a is the initial value of f(x)
- The domain of the function is all the values of x which make the
function defined
- The range of the function is the set of values of y that corresponding
with the domain x
- Asymptote on the graph a line which is approached by a curve but
never reached
- A function of the form f(x) = a(b^x) + c always has a horizontal
asymptote at y = c
* Lets solve the problem
∵ h(x) = (0.5)^x - 9
∵ All the values of x make h(x) defined
∵ The domain of the function is the values of x
∴ The domain of h(x) is {x : x ∈ R} ⇒ R is the set of real number
∵ The range of the function is the set of values of y which
corresponding to x
∵ (0.5)^x must be positive because there is no values of x make it
negative value
∴ y must be greater than -9
∴ The range of the function is {y : y > -9}
∵ A function of the form f(x) = a (bx) + c always has a horizontal
asymptote at y = c
∵ h(x) = (0.5)^x - 9
∴ c = -9
∴ The horizontal asymptote is at y = -9

Answer:
y-intercept = (0, ).
Step-by-step explanation:
Given the linear equation in standard form, 12x + 13y = 8:
We must transform this equation into slope-intercept form to make it easier to determine the coordinates of the y-intercept.
12x + 13y = 8
Subtract 12x from both sides:
12x + 13y - 12x = - 12x + 8
13y = - 12x + 8
Next, divide both sides of the equation by 13 to solve for y:
or
Next, to determine the y-intercept, we must set x = 0 (because the y-intercept is the point where the graph of the linear equation crosses the y-axis).
Let x = 0:
Therefore, the value of y when x = 0 is . This is the y-intercept, and its coordinate is (0,
).
