Question

the points (3,48) and 5,768) lie on the graph of an exponential function. write the equation in exponential form. Must explain or I'll report! answer asap!

Answer 1

• y = 3/4*4ˣ

Explanation:

The function is:

• y = abˣ

Substitute the values from the given points and solve for b:

• 48 = ab³
• 768 = ab⁵

Divide the second equation by the first one:

• 768/48 = ab⁵/ab³
• b² = 16
• b = 4

Find a using the first equation:

• 48 = a*4³
• a = 48/64
• a = 3/4

The function is:

• y = 3/4*4ˣ
