Considering the scatter plot, the function that best fits the data is given by:

f(x) = 3x².

<h3>What is the function that best fits the data?</h3>

To find the function that best fits the data, we have to look at the scatter plot, which gives a series of points (x,y).

We have that:

  • When x increases, y also increases, hence the function is increasing, which removes the option f(x) = -3x.
  • The increase looks "faster" than a linear increase, hence a quadratic model should be used, thus removing option f(x) = 3x.

Hence the function that best fits the data is given by:

f(x) = 3x².

Simplify completely x^2+4x-5/5x^2-8x+3
arlik [135]

Answer:

\boxed{\bold{\frac{x+5}{5x-3}}}

Explanation:

[ Step One ] Factor \bold{x^2+4x-5}

\bold{x\left(x-1\right)+5\left(x-1\right)}

[ Step Two ] Rewrite Equation

\bold{\frac{\left(x-1\right)\left(x+5\right)}{5x^2-8x+3}}

[ Step Three ] Factor \bold{5x^2-8x+3}

\bold{\left(x-1\right)\left(x+5\right)}

[ Step Four ] Rewrite Equation

\bold{\frac{\left(x-1\right)\left(x+5\right)}{\left(5x-3\right)\left(x-1\right)}}

[ Step Five ] Cancel Out Common Factor \bold{x-1}

\bold{\frac{x+5}{5x-3}}

\boxed{\bold{Mordancy}}

Name each expression by the number of it's terms. Use monomial, binomial, trinomial, and polynomial
Kobotan [32]

Answer:

1. Binomial 2. Trinomial 3. Trinomial 4. Polynomial 5. Polynomial 6. Polynomial 7. Trinomial 8. Binomial 9. Polynomial 10. Monomial

Step-by-step explanation:

For future references, you can use this to find out what the expression (number of its terms) is...

Monomial > One term = 2x^5

Binomial > Two terms = x^2 + 5

Trinomial > Three terms = 3x - 8 + 4x^5

Polynomial > Four terms (or more) = -7a^2 + 9b - 4b^3 + 6
