It would be hard to figure out 10 to what power is 235. It will end up being a decimal. We will have to evaluate this logarithm on your calculator! We are not sure what calculator you have but if you have a scientific calculator, usually the log function thinks you are in base 10. Find the log button on your calculator and type log 235.
The exponential functions we'll deal with here are functions of the form. y = ab (linear function of x) + c. where a and c are real numbers, and b is greater than 1. Really, this just means we have a number greater than 1 getting raised to the x.
Concave and Convex Functions Intervals of Concavity and Convexity Study the intervals of concavity and convexity of the following function: f(x) = x³ − 3x + 2 To study the concavity and convexity, perform the following steps: 1. Find the second derivative and calculate its roots. f''(x) = 6x 6x…

Use calculator’s table function to check your values. Students will experiment with different types of functions like linear and higher power polynomials. Let’s discuss what different types of functions you were able to come up with. Explanation: Today we’re going to talk about a new type of function. They’re exponential functions.

Evaluate exponential functions. Recall that the base of an exponential function must be a positive real number other than 1. Why do we limit the base b to positive values? In more general terms, we have an exponential function, in which a constant base is raised to a variable exponent.
