# What is the rate of change for f(x) = 7sinx - 1 on the interval from x = 0 to x = pi/2?

**Solution:**

The average rate of change of a function f(x) is equivalent to the slope of the secant line connecting the two points on the function on the interval [a, b]. It can be expressed as:

average rate of change = [f(b) - f(a)]/ b - a

f(π/2) = 7 × sin(π/2) - 1

= 7 × 1 - 1 = 6

f(0) = 7 × sin(0) - 1

= 0 - 1 = -1

The rate of change = (6 + 1)/(π/2 - 0) = 14/π

## What is the rate of change for f(x) = 7sinx - 1 on the interval from x = 0 to x = pi/2?

**Summary:**

The rate of change for the function f(x) = 7sinx - 1 on the interval from [0, π/2] is 14/π.
