Given the function g(x) = 8x − 2, compare and contrast g(−2) and g(4). Choose the statement that is true concerning these two values.

The value of g(−2) is larger than the value of g(4).
The value of g(−2) is the same as the value of g(4).
The value of g(−2) is smaller than the value of g(4).
The values of g(−2) and g(4) cannot be compared.

To find the value of g(-2) you replace every copy of x with -2. Then you simplify

jim_thompson5910 · Answer

g(x) = 8x - 2
g(-2) = 8(-2) - 2 ... replace every x with -2
g(-2) = -16 - 2
g(-2) = -18

hopefully this makes sense?

oswaldmurphy · Answer

Why -2, because that is the first one of the two so it = x?

jim_thompson5910 · Answer

because it says "contrast g(-2) and g(4)"

jim_thompson5910 · Answer

I showed how to get g(-2), which is -18

are you able to find g(4) ?

oswaldmurphy · Answer

Oh so I have to do both. Ok it makes since now. g(4) = 30?

jim_thompson5910 · Answer

g(4) = 30 is correct

oswaldmurphy · Answer

So the answer is C?

jim_thompson5910 · Answer

yep ` The value of g(−2) is smaller than the value of g(4).` is correct
