Question

Which of the following is the function representing the graph below?

A. f(x) = 4x
B. f(x) = 4x − 3
C. f(x) = 4x + 3
D. f(x) = 4(x + 3)

Answer 1

please help , i'm pretty sure the answer is C

Answer 2

@pooja195

Answer 3

@Nnesha you're a genius please help

Answer 4

you listed straight line graphs, the graph is a curve...

Answer 5

oh i forgot the last option is f(x) = 4^(x + 3)

Answer 6

these are the options they gave me.. @amorfide

Answer 7

@Gabylovesyou @ElonaSushchik @Nnesha

Answer 8

well it will have to be f(x) = 4^(x + 3) because the others are straight line graphs
and the only way to get a curve in this case I would believe to be logs

\[y=4^{(x+3)}\]

then you look at the graph given and you wanna substitute the negative x values to see what y values you get, draw the graph
see if it matches

you will most likely have to take the natural log of both sides to get

\[lny=\ln4 ^{(x+3)}\]

\[lny=(x+3)\ln4\]

Answer 9

i'm not sure because usually i just graph the options and whatever it is , it matches with the graph but this one seems complicated , i picked c because it's going 3 to the left but i'll go with D as you said

Answer 10

if you look at answer choices only u can easily find your answer
y = mx + b this is linear equation which suppose to be straight line

Answer 11

A. f(x) = 4x
B. f(x) = 4x − 3
C. f(x) = 4x + 3
D. f(x) = 4(x + 3)


A has a gradient of 4 the graph does not
B has a y intercept of -3 the graph does not
C has a y intercept of 3 the graph does not
D has a y intercept of 12 from the looks of it the graph does not
E is your only option

Answer 12

or you can look at the gradient for A B C and D they all have a gradient of 4 the graph shown does not

Answer 13

and there is no E rofl wait give him a chance to think about it

Answer 14

there is an E
E is f(x) = 4^(x + 3)

Answer 15

ohh welll u already gave him a answer
but that is D

Answer 16

oh there is no E , D is f(x) = 4^(x + 3) but i wrote it wrong i'm sorry

Answer 17

y = mx + b linear equation which mean straight line
if you focus on this in this equation none of variable have exponent so

Answer 18

lol oh my bad

Answer 19

so it's C right , because it's going 3 to the left?

Answer 20

there is only one equation with exponent

Answer 21

\[\huge\rm C) f(x) = 4x + 3\] is there any exponent ??

Answer 22

the answer has to have an exponent?

Answer 23

there is not any exponent
