Math
Indefinite IntegrationIdentify a function f that has the given characteristics. Then sketch the function.
f(0) = 3
f'(x) = 3,00 < x < 00
Step 1
We are given f '(x) = 3, ∞0 < x < . This means the derivative of our function f is constant for all real
numbers. Another way to think of this is that the slope of the tangent line to f is the same regardless of where
we are on f. What type of function has a constant slope?
linear
cubic
exponential
quadratic
Step 2
We determined that f is a linear function, and we know f '(x) is the slope. Write the general form of a linear
function replacing the slope with f '(x).
f(x) = mx + b
