F(x)=13.49(0.967) x -1 is the function that explains how many o-rings are expected to fail as the temperature changes (falls). Exponential functions – variable in the exponent – are used in looking at population growth, epidemics, radioactive decay, credit card payments, investment interest, etc.

At launch time, the temperature at the Kennedy Space Center was 36 degrees Fahrenheit. This was 15 degrees colder than any previous Space Shuttle launch. All of Challenger's pre-launch preparations were routine, with the exception of tremendous ice buildup on the launch pad that formed as temperatures dipped into the low 20's overnight.

Use a calculator to compute: /3 6 2/3 4 √ √14641

The Natural Base e It’s value is approximately

Calculate: e5.1 e-4 e1/2

Which of these functions are equal? F(x) = 4 x + 12 F(x) = 4 x + 12 G(x) = 2 2x+6 G(x) = 2 2x+6 H(x) = 64(4 x ) H(x) = 64(4 x )

Which of these functions are equal? F(x) = 16(4 -x ) F(x) = 16(4 -x ) G(x) = (1/4) x-2 G(x) = (1/4) x-2 H(x) = (16)(2 -2x ) H(x) = (16)(2 -2x )

Which of these functions are equal? F(x) = 3 x-2 F(x) = 3 x-2 G(x) = 3 x -9 G(x) = 3 x -9 H(x) = (1/9)(3 x ) H(x) = (1/9)(3 x )
