Answer:

-2x² + 15

Step-by-step explanation:

Step 1: Add like terms

4x² - 6x² = -2x²

-10x + 10x = 0

3 + 12 = 15

Step 2: Rewrite

-2x² + 15

aleksley [76]

Answer:

Given equation:   y=(x+1)^2-2

The function is a <u>quadratic function</u> in <u>vertex form</u>:  y=a(x-h)^2+k

<u>Translations</u>

For a > 0

f(x+a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units left}

f(x-a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units right}

f(x)+a \implies f(x) \: \textsf{translated}\:a\:\textsf{units up}

f(x)-a \implies f(x) \: \textsf{translated}\:a\:\textsf{units down}

Parent function:  f(x)=x^2  

<u>Translations</u>

Translated 1 unit left:  f(x+1)=(x+1)^2

Then translated 2 units down:  f(x)-2=(x+1)^2-2

Therefore, translate the parent function by <u>1 unit left</u> and <u>2 units down</u> to produce the given equation.
