an exponential function of form f(x)=b^x includes the points (2, 16), (3, 64), and (4, 256) what is the value of b

timofeeve [1]

The value of b is 4

Step-by-step explanation:

The form of an exponential function is $f(x)=a(b)^{x}$ , where

a is the initial value (value f(x) at x = 0
b is the growth/decay factor
T find the values of a and b substitute x and f(x) by the coordinates of any points belong to the function

∵ $f(x)=b^{x}$

∵ The function includes the points (2 , 16) , (3 , 64) , (4 , 256)

- To find b substitute x and f(x) by the coordinates if any point above

∵ x = 2 and f(x) = 16

∴ $16=(b)^{2}$

- Take √ for both sides

∴ ± 4 = b

Substitute x by 3 and f(x) 64 to check your answer

∵ $64=(b)^{3}$

- Take ∛ for both sides

∴ 4 = b

∴ The value of b is 4 only

The value of b is 4

Find an equation of the line that goes through the points (10,34) and (-1,10)

kotykmax [81]

Answer:

Given points are ( 10 ,34 ) and ( -1 , 10)

Step-by-step explanation:

The equation of line is given by 

first we can find slope (m) 

= (y2 - y1) / ( x2 - x1)

= 34-10/10+1

 =24/11

Now the equation is

y - y1 = m ( x - x1) 

y - 10 = 24/11 ( x +11)

11 ( y - 10 ) = 24 (x + 11)

11y - 110 = 24x + 264

24x + 264 +110-11y =0

24x - 11y + 374 = 0

which is the required equation
