The increase in pressure P (in pounds per square in, or psi) is a linear function of the depth d (in feet) to which a suba diver descends. This function, P(d)= 0.445d+ 14.7 1.) Which is the initial value? What does is represent?
2) What is the rate of change? What does it represent?

Step-by-step explanation:

sorry it's is so hard sorry

is only a line? i think so

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
