What is the domain and range of f(x)=4^x-8

gladu [14]

If the function is: f(x) = 4^x - 8

D = {XeR}
R = {YeR|Y≥0}

if the function is: f(x)=4^(x-8)

D = {XeR}
R = {YeR|Y≥ -8}

1. Mark each of the following graphs as (a) a function, but not one-to-one, (b) one-to-one function, or (c) not a function. In e

Helen [10]

Answer:

(a) a function, but not one-to-one

Step-by-step explanation:

The graph is of a function if it passes the vertical line test: a vertical line intersects the graph in at most 1 point.

The function is one-to-one if it passes the horizontal line test: a horizontal line intersects the graph in at most 1 point.

Here, the graph consists of a series of non-overlapping horizontal lines. It passes the vertical line test (is a function), but a horizontal line can intersect the graph in an infinite number of points (is not one-to-one).

The graph is a function, but not one-to-one.

Steve kicks a football into the air. The path that a ball takes can be described by the equation h=20t - 5t squared where h is t

FinnZ [79.3K]

Since h represents the height of the ball at any given time, t, let h = 25, such that the ball will be 25m high at t.

Now, we have 25 = 20t - 5t²
5t² - 20t + 25 = 0
t² - 4t + 5 = 0

$\frac{4 +- \sqrt{16 - 20}}{2}$

Since the discriminant is less than zero, there are no solutions.
Hence, the ball will never be 25m high.
