Answer:

Mode = 7

Median = 6

Mean = 5.2

Range = 7

Step-by-step explanation:

Mode:

The most repeated number is 7 (thrice).

Median:

First, arrange them in order.

1, 2, 3, 4, 5, 7, 7, 7, 8, 8

The two middle numbers are 5 and 7. Find their average.

(5 + 7)/2 = 6

Mean:

(3+7+2+4+7+5+7+1+8+8)/10 = 5.2

Range:

Largest number - smallest number

8 - 1 = 7

Which ordered pairs lie on the graph of the exponential function f(x)=2^(x+4)−8?

natka813 [3]

Given the function

$f(x)=2^{(x+4)}-8$

Consider the point (2, 56) i.e. when x = 2

$f(x)=2^{2+4}-8 \\ \\ =2^6-8=64-8 \\ \\ =56$

Therefore, point (2, 56) lie on the graph of the given exponential function.

Consider the point (-2, -4) i.e. when x = -2

$f(x)=2^{-2+4}-8 \\ \\ =2^2-8=4-8 \\ \\ =-4$

Therefore, point (-2, -4) lie on the graph of the given exponential function.

Consider the point (8, 0) i.e. when x = 8

$f(x)=2^{8+4}-8 \\ \\ =2^{12}-8=4,096-8 \\ \\ =4,088$

Therefore, point (8, 0) does not lie on the graph of the given exponential function.

Consider the point (24, 1) i.e. when x = 24

$f(x)=2^{24+4}-8 \\ \\ =2^{28}-8=268,435,456-8 \\ \\ =-268,435,448$

Therefore, point (24, 1) does not lie on the graph of the given exponential function.
