The approximate age of a woman whose normal systolic pressure measures 125 mm Hg is 31
The function is given as:
When the normal systolic pressure is 125, it means that:
So, we have:
Subtract 125 from both sides of the equation
Rewrite the equation as:
Using a graphing calculator, we have:
But age cannot be negative.
So, we have:
Approximate
Hence, the age of the woman is 31
