Decide if the function is an exponential function. if it is, state the initial value and the base.

y = - 7.3 ⋅ 2x

exponential function; base = - 14.6; initial value = 1
exponential function; base = x; initial value = - 7.3
not an exponential function
exponential function; base = 2; initial value = - 7.3

Of four points are collinear, they are also coplanar

The swimming pool is open when the high temperature is higher than 20∘c. lainey tried to swim on monday and thursday (which was 33 days later). the pool was open on monday, but it was closed on thursday. the high temperature was 30 ∘c on monday, but decreased at a constant rate in the next 33 days. write an inequality to determine the rate of temperature decrease in degrees celsius per day, d, from monday to thursday.

Which points are solutions to the linear inequality y < 0.5x + 2? check all that apply. (–3, –2) (–2, 1) (–1, –2) (–1, 2) (1, –2) (1, 2)
