F(x) = 2x2 – 5x – 20 Find f (-9​
Anna [14]

Answer:

<h2>f( - 9) = 187</h2>

Step-by-step explanation:

f(x) =  {2x}^{2}  - 5x - 20

To find f(-9) , substitute the value of x that's -9 into f(x). That is for every x in f (x) replace it with - 9

We have

<h3>f( - 9)  = 2 ({ - 9})^{2}  - 5( - 9) - 20 \\  = 2(81) + 45 - 20 \\  = 162 + 25 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:</h3>

We have the final answer as

<h3>f( - 9) = 187</h3>

Hope this helps you
