x g(x)
1 6
2 8
3 12
the function h of x equals 4 to the x power, plus 3 j(x) = 10(2)x

Answer 1

@ganeshie8

Answer 2

f(x) is blake
g(x) x
1 6
2 8
3 12
h(x)
the function h of x equals 4 to the x power, plus 3
j(x) 10(2)x

Answer 3

i wrote it more organized here @ganeshie8

Answer 4

a screenshot would have helped..

Answer 5

i can't take a screenshot

Answer 6

y intercept is the value at x = 0,
its same as the `starting value`

Answer 7

whats the starting value for f(x) ?

Answer 8

6

Answer 9

good, so y intercept for f(x) is 6

Answer 10

g(x) the highest y-intercept is 12
h(x) the highest intercept there would be 4
correct

Answer 12

nope, i may not be able to help you with out a screenshot - i don't trust if the question was copied accurately...

Answer 13

that is for the graph of h(x)

Answer 14

whats the issue in taking a screenshot and attaching ?

Answer 15

because my laptop does not do that but i did the best to redo the graph here

Answer 16

your best is very confusing, nobody can draw these graphs clearly

Answer 17

a screenshot is required, and trust me you can take a screenshot -
spend few seconds in knowing how to take the screenshot

Answer 18

@ganeshie8

Answer 19

i just posted it

Answer 20

i had gotten g(x) as a response

Answer 21

ty :) thats a good guess, but the correct answer is j(x)

Answer 22

y intercept is the y value when x = 0
for g(x), y value can be less than 6 when x = 0

Answer 23

whereas y intercept of j(x) is 10 which is apparently greater than other 3 functions

Answer 24

oh ok thanks
Given the exponential function A(x) = P(1 + r)x, what value for r will make the function a decay function?

r = −2.1

r = 2.1

r = 0

r = 0.1
