Answer:

3. f(x) = 5^x

4. f(x) = 3 (8)^x

Step-by-step explanation:

3. Which function represents the data 2=>25, 3=>125, 4 =>625

You just have to plug the values of x in the equations provided and see which one fit, you stop testing for a given equation when it doesn't match the data table.

f(x) = x^4 + 9 - NO

for x = 2, 2^4 + 9 = 16 + 9 = 25 YES

for x = 3, 3^4 + 9 = 81 + 9 = 90 NO, should be 125

f(x) = 4^x + 9 - NO

for x = 2, 4^2 + 9 = 16 + 9 = 25 YES

for x = 3, 4^3 + 9 = 64 + 9 = 73  NO, should be 125

f(x) = x^5 - NO

for x = 2, 2^5 = 32 NO, should be 25

f(x) = 5^x YES

for x = 2, 5^2 = 25  YES

for x = 3, 5^3 = 125  YES

for x = 4, 5^4 = 625  YES

4. Which of the options is equivalent to f(x) = 3(2)^(3x)

By property of the powers you can easily break down the 3x exponent into a much simpler way.

(2)^{3x} = (2^{3} )^{x} = 8^{x}

From (2)^(3x) we got to 8^x, so the equation can now be written:

f(x) = 3 (8)^x, which is the first choice.

You could easily verify it with x = 2 in each equation.

Find the rate of change of the linear function shown in the graph. Then find the initial value.
EastWind [94]

rate of change is change in y / change in x


(-1 - -3)/ (0 - -6) = 2/6 = 1/3


initial value is the y value when x is 0 , which is -1

Pepsi [2]
If you add 55% and 45% the total is 100%   so 45/100 are girls.  35% of the girls scored and A  so 35/45  is the probability that it is a girl chosen or 7/9. the probability is 7 out of 9
