1/2 is the contradiction I think.

What’s the range on the graph?

Contact [7]

Answer:

The answer to your question is -4 to infinite

Step-by-step explanation:

Range is the set of all the possible values of the dependent variable when substitute the domain in the function.

On a graph, we find the range, looking at all the y-axis

In this graph, y has values from -4 to infinite, then, the range is [-4, ∞)

Rina8888 [55]

By definition, electromagnetic induction is the term that is generally used to describe the method of generating a potential difference across a conductor through a changing magnetic field. In addition, the induce current would be minimised if the loop is placed parallel to the magnetic field itself. Therefore, C.

Answer:

a/8 = b/15

Step-by-step explanation:

a/b = 8/15 -- divide both side by 8 and multiple both side by b

Using an exponential function, it is found that f(5.5) = 19.8.

<h3>What is an exponential function?</h3>

An exponential function is a function in which the growth rate is a percentage, modeled by:

$y = ab^x$

In which:

a is the initial value.

b is the rate of change.

f(3.5) = 25 means that:

$ab^{3.5} = 25$

$a = \frac{25}{b^{3.5}}$

f(8.5) = 14 means that:

$ab^{8.5} = 14$

Hence:

$\frac{25}{b^{3.5}} \times b^{8.5} = 14$

$25b^5 = 14$

$b = \sqrt[5]{\frac{14}{25}}$

$b = 0.89$

$a = \frac{25}{0.89^{3.5}} = 37.59$

Hence, the function is given by:

$y = 37.59(0.89)^x$

Then, when x = 5.5:

$f(5.5) = 37.59(0.89)^{5.5} = 19.8$
