How can you find f(3) if f(x) = -2x^2 - 4? a) square 3. subtract 4 from the result, and then multiply by -2 b) square 3. multiply the result by -2, and then subtract 4 c) multiply 3 by f d) multiply -2 by 3, square the result, and then subtract 4

B

Step-by-step explanation:

By order of operations, we have to do the squaring of the 3 first.  After that, we have to tackle multiplication or division, whichever we come to first in the equation.  That means that we multiply the square of 3 by -2.  After we do that, all of the multiplication/division is done and we can do the addition/subtraction next which, in our case, is to subtract away 4.  

y - y1 = m(x- x1)

y - (-5) = 2/3(x -0)

y + 5 = 2/3x

y = 2/3x - 5

f(x) = y

f(-3) = -5
