Answer:

a) The minimum y-value of f(x) is -3

d) The minimum y-value of g(x) is -3

Step-by-step explanation:

Given in the question that,

f(x) = 3 $^{x}$ -3

g(x) = 7x² - 3

At large negative exponents, the value approaches to zero

y = $3^{-100}-3=-3$

y = $3^{-1000}-3=-3$

y = $3^{-10000}-3=-3$

Minimum y-value of g(x) will be when x = 0

y = 7x² - 3

y = 7(0) - 3

y = -3

Quincy claims that if 80 coats are sold, the outside temperature is likely to be about 42°

nikklg [1K]

No. Quincy should have used the trend line to find the corresponding x value when y=80.

Step-by-step explanation:

i) $\overline{AB} = \sqrt{(x_A - x_B)^2 + (y_A - y_B)^2}$

$\:\:\:\:\:\:\:=\sqrt{(2)^2 + (12)^2} = 12.3$

ii) $m = \dfrac{y_A - y_B}{x_A - x_B} = \dfrac{-12}{2} = -6$

iii) $(\overline{x},\:\overline{y}) = \left(\dfrac{x_A + x_B}{2},\:\dfrac{y_A + y_B}{2}\right)$

$\:\:\:\:\:\:\:=(3,\:-2)$
