Question

The following table shows the values of f(x) and g(x) for different values of x:


x 1 2 3 4 5
f(x) 5 25 125 625 3.125
g(x) -3 -3 -3 -3 -3


Which of the following best describes the function f(x) + g(x)?
5x – 3x

–3(5x)

5x – 3

5x – 3

Answer 1

dat pic, going to get you in trouble with preetha >.>

Answer 2

@superdavesuper

Answer 3

g(x) is always -3
f(x) should be 5^x

Answer 4

so A ?

Answer 5

a is 5^x-3x

Answer 6

i would go with \(5^x-3\) as well

Answer 7

or c? 5^x-3

Answer 8

if that is an option

Answer 9

yeah, C
it is always C

Answer 10

yea it is, its C, ok that makes more sense

Answer 11

yeah seems you misstyped the answers in your question

Answer 12

Well, f(x) is being squared, 5^2 = 25 5^3 = 125

So, 5^x - 3

Answer 13

ok how about this question ?

The table below shows the average temperature, in degrees Celsius, in Jacob's city over a period of five months:


Month 1 2 3 4 5
Temperature 5 7.2 9.4 11.6 13.8


Did the temperature in Jacob's city increase linearly or exponentially?
Linearly, because the table shows a constant percentage increase in temperature each month.

Exponentially, because the table shows a constant percentage increase in temperature each month.

Linearly, because the table shows that temperature increased by the same amount each month.

Exponentially, because the table shows that temperature increased by the same amount each month.

Answer 14

i think its D

Answer 15

Well, the average rate of change is 2.2, 5 + 2.2 = 7.2

7.2 + 2.2 = 9.4

9.4 + 2.2 = 11.6

So clearly its linear

Answer 16

it increases by 2.2 every time so c ?

Answer 17

Ya

Answer 18

ok that was easier than it seemed
