Find the minimum or maximum of the function. Describe the domain/range in interval notation y=6x^2-1

Margarita [4]

max is at vertex

in form $y=ax^2+bx+c$

the x value of the vertex is $\frac{-b}{2a}$

given, $y=6x^2-1$

a=6, b=0

the x value of the vertex is -0/(2*6)=0

the y value is $y=6(0)^2-1=0-1=-1$

so vertex is at (0,-1)

since the value of a is positive, the parabola opens up and the vertex is a minimum value of the function

therefore that value is the smallest value the function can be

domain=numbesr you can use for x

range=numbesr you get out of inputting the domain

domain=all real numbers

range is {y | y≥-1} since y=-1 is the minimum

Answer:

Step-by-step explanation:

Perpendicular lines are lines whose slopes are negative reciprocals of each other

To find the slope of the line we are given, we can rearrange the equation

$4x - 5y = 4\\4x - 4 = 5y\\y = \frac{4}{5}(x) - \frac{4}{5}$

The slope of this line is $\frac{4}{5}$ , so the slope of the other line is $\frac{-5}{4}$

next, we can use the given point to find the equation $y = mx +b$

we know m, we can solve for b

$y = \frac{-5}{4}(x) + b\\-3 = \frac{-5}{4}(-2) + b\\-3 = \frac{5}{2} + b\\\frac{-6}{2} = \frac{5}{2} + b\\$

$b = \frac{-11}{2}$

$so,\\y = \frac{-5}{4}(x) - \frac{11}{2}$

ASAAPPPPPP!!!!! Complete the tables of values

velikii [3]

Answer:

see explanation

Step-by-step explanation:

Using the rules of exponents

$a^{-m}$ ⇔ $\frac{1}{a^{m} }$ and $a^{0}$ = 1

Substitute the values of x into $4^{-x}$

x = 0 → $4^{0}$ = 1 ⇒ a = 1

x = 2 → $4^{-2}$ = $\frac{1}{4^{2} }$ = $\frac{1}{16}$ , hence

b = $\frac{1}{16}$

x = 4 → $4^{-4}$ = $\frac{1}{4^{4} }$ = $\frac{1}{256}$ , hence

c = $\frac{1}{256}$
