The growth of outpatient surgeries as a percent of total surgeries at hospitals is approximated by f(x)=-1317+304㏑x

where x is the number of years since 1900. (Source: American Hospital Association)

In what year did outpatient surgeries reach 50%? (Hint: Substitute for y, then write the equation in exponential form to solve it.)

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
