<h2><u>Answer:</u></h2><h2>y=x^2 has an inverse but it is not a function</h2><h2><u>Step-by-step explanation:</u></h2><h2>y = x</h2><h2>y=x has an inverse function. y=x is the equation of a line. All line has an inverse function and it is also a function</h2><h2>y = 2x + 1 is the equation of a line.</h2><h2>All line has an inverse function and it is also a function</h2><h2>y = x^2 is the equation of a quadratic Quadratic equation has an inverse but it does not pass vertical line test.Hence it is not a function</h2><h2><u></u></h2><h2><u>Thank you</u></h2><h2><u>sunshinemadison101</u></h2>

Nathan is a recreational cyclist. He can travel 10 miles in one hour on his bicycle. Which graph represents the number of miles

PolarNik [594]

Answer:

See attachment for graph

Step-by-step explanation:

Given

$1\ hr = 10\ miles$

Required

The graph that shows the number of miles in x hours

We have:

$1\ hr = 10\ miles$

Multiply both sides by x

$x * 1hr = 10miles * x$

$xhr=10x\ miles$

So, the function is:

$f(x) =10x$

1. if h(x)=(fog)(x) and h(x)=3sqrt7x+1, find f(x) and g(x)

xeze [42]

1. h(x) = 3 $\sqrt{7x+1}$

Let f(x) = 3x and g(x) = $\sqrt{7x+1}$

2. N(x) = ( $\sqrt{2x}$ )⁵

Let f(x) = x⁵ and g(x) = 2x and h(x) = $\sqrt{x}$

What is the solution to the system of equations?

vesna_86 [32]

The correct answer is (10,-20), because the equation already gives you the correct x value. Then, from there you just plug 10 in for x in the y equation. Giving you a -20, :)

Write children 3 and under free as an inequality

Valentin [98]

Answer:

Children ≤ 3 (are free)

Step-by-step explanation:

This is strangely worded by I think this is what you were looking for.

The key take away is, if it says something and under, you know it means that it can either be exactly that "something" or anything that is less than it, so you would use the less than or equal to symbol.
