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.

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
