Question

What is the exponential function modeled by the following table?


x f(x)
2 9
3 27
4 81
f(x) = x3

f(x) = 3x

f(x) = x2 + 5

f(x) = 2x + 5 @$w3G_Godd

Answer 1

x^3
3^x
x^2+5
2^x+5

Answer 2

Just plug in x value in each choice and see which one gives you the corresponding f(x).

Also the x is exponent in all the choices.

Answer 3

I got B

Answer 4

In what direction and by how many units is the graph of f(x) = 6 sin(2x + π) − 5 vertically and horizontally shifted?

Down 5, left pi over 2

Up 5, left pi over 2

Down 5, right pi over 2

Up 5, right pi over 2

Answer 5

hold on

Answer 6

ok

Answer 7

k im back

Answer 8

i actually dont know the answer to this one

Answer 9

What is the x-coordinate for the minimum point in the function f(x) = 4 cos(2x − π) from x = 0 to x < 2π?

x = pi over 2

x = pi over 4

x = 2π

x = π

Answer 10

ok

Answer 11

What is the logarithmic function modeled by the following table?

x f(x)
9 2
27 3
81 4
f(x) = logx3

f(x) = 3 log10x

f(x) = x log103

f(x) = log3x

Answer 12

the answer is

f(x)=log3x

Do u need explanation ?

Answer 13

no

Answer 14

What function best represents a sine function with an amplitude of 4, a period of pi over 6, and a midline at y = −2?

f(x) = −2 sin(x − pi over 6) + 4

f(x) = 4 sin 12x − 2

f(x) = 4 sin(x − pi over 6) − 2

f(x) = −2 sin 12x + 4
