Directions: Use the integers 1-9, without repetition, to fill in the empty spaces so that the equation with the definite integral is true.

### Hint

The integral represents the area under the curve. What does this look like on a graph?

### Answer

Multiple answers.

Integral from 2 to 4 of 3x-5 equals 8. (This would have to be formatted as an equation).

Please consider revising the stem to replace “the numbers 1-9” with either “the integers 1-9” or “the digits 1-9”. Although I expect that was the author’s intended number set, as written it is ambiguous.

Thank you!

Agreed Diana. I’ll make the change.

I love these activities. I just put this one into Desmos Activity builder to use it as a warm up.
