The height of an object above the ground in feet can be modeled as a function of time, t, in seconds using the equation: h(t)= -

11111nata11111 [884]

Answer:

(a) t = 7 sec approximately; (b) t = 6 sec

Step-by-step explanation:

(a) Set h(t)= -16(t-3)^2 + 288 = 0 and solve for t:

16(t-3)^2 = 288

After simplification, this becomes (t - 3)^2 = 18, or t - 3 = ±3√2.

Because t can be only zero or positive, t = 3 + 3√2 = 7 seconds

(b) Solve h(t)= -16(t-3)^2 + 288 = 150:

-16(t-3)^2 = - 162

or (t - 3)^2 = 10.125, or

t - 3 = ±3.18, or, finally, t = 6.18 sec (discard t = -0.18 sec)

The function f(x) is a polynomial, while the function g(x) is a logarithmic function and the functions have the same range

<h3>The type of functions</h3>

The functions are given as:

f(x) = x³ + x² - 2x + 3

g(x) = log(x) + 2

The function f(x) is a polynomial, while the function g(x) is a logarithmic function.

<h3>The key features</h3>

For the polynomial function, we have:

Domain: -∞ < x < ∞
Range: -∞ < x < ∞
y-intercept = 3

For the logarithmic function, we have:

Domain: x > 0
Range: -∞ < x < ∞
y-intercept = undefined

By comparison, the functions have the same range
