Answer: 2

<u>Step-by-step explanation:</u>

f(x) = 2x + 3 g(x) = x² - 1

f(g(x)) = f(x² - 1)

= 2(x² - 1) + 3

= 2x² - 2 + 3

= 2x² + 1

The largest exponent is 2 so the degree is 2.

If f(x)=4x+9+2, which inequality can be used to find the domain of f(x

Ksju [112]

First off, the function above is incomplete, however, by the looks of it, likely a quadratic, anyway, the values "x" can safely take on would be all real numbers, thus -∞ < x < +∞

Explain how proving two triangles congruent can help prove parts of the triangle congruent.

Ierofanga [76]

You can use the CPCTC (Corresponding Parts of Congruent Triangles are Congruent) property. This means that when two triangles are congruent, all the corresponding parts are congruent to each other.

Have an awesome day! :)
