Which equation represents an exponential function that passes through the point (2, 80)? f(x) = 4(x)5
f(x) = 5(x)4
f(x) = 4(5)x
f(x) = 5(4)x

Step-by-step explanation:

We can plug the coordinates given into each equation.

We replace f(x) with the y coordinate (80) and the x with x coordinate (2)

Divide each side by 5

Square root each side

4=4 This statement is true there fore it is your answer.

Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
