Answer:

g(-2) = -6

g(0) = 0

g(5) = 15

Step-by-step explanation:

For each of the evaluations, you have to plug in the number everywhere where there is an x

DedPeter [7]

Answer:

use own words

Step-by-step explanation:

An expression is just a mathematical phrase. In this tutorial, you'll learn about two popular types of expressions: numerical and algebraic expressions. A numerical expression contains numbers and operations. An algebraic expression is almost exactly the same except it also contains variables.

in mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number)

-2. H(x) is the transformation of the parent

elena-s [515]

If the function f(x) is translated 7 units right and 8 units up, then the equation of h(x) is h(x) = $(x+7)^2$ + 8

The given function is

f(x) = $x^2$

Here f(x) is translated 7 units right and 8 units up

The translation is the process of changing the coordinates of the shape in the graph

The given function is

f(x) = $x^2$

First the function is translated 7 units right

Then the function will become

f(x) = $(x+7)^2$

Then the function is translated 8 units up

Then the function will become

h(x) = $(x+7)^2$ + 8

Hence, if the function f(x) is translated 7 units right and 8 units up, then the equation of h(x) is h(x) = $(x+7)^2$ + 8

Find the range of y = 3/2 cos 4x - 1

motikmotik

Answer:

B. $-2\frac{1}{2} \leq y \leq \frac{1}{2}$

Step-by-step explanation:

The given trigonometric function is

$f(x)=\frac{3}{2}cos4x-1$ .

The amplitude of this function is $\frac{3}{2}$ , so under normal circumstances the range is supposed to be

$-\frac{3}{2} \leq y \leq \frac{3}{2}$

But the $-1$ is a downward vertical shift.

Therefore the normal boundaries of the range will shift down one unit to give the range of the transformed function.

We subtract 1 from the lower boundary to get $-\frac{3}{2}-1=-2\frac{1}{2}$

We also subtract 1 from the upper boundary to get $-frac{3}{2}-1=\frac{1}{2}$

Hence the range is

$-2\frac{1}{2} \leq y \leq \frac{1}{2}$
