Find the range of the function rule y=5x-2 for each domain. {-1.2, 0, 4}

2 answers:

5 0

Domain is inputs, input the domain for x
y=5(-1.2)-2
y=-6-2
y=-8

y=5(0)-2
y=0-2
y=-2

y=5(4)-2
y=20-2
y=18

range is {-8, -2, 18}

3 0

For x = 0,
we substitute zero into the equation to find its y value like so:

y = 5x-2

y = 5(0)-2

y = -2
There you go.

Answer: First option

Step-by-step explanation:

By definition, the horizontal shift depends on the value of h and the vertical shift depends on the value of k.

$f(x)=(x-h)^3$ indicates that the function if shifted to the right h units.

$f(x)=(x+h)^3$ indicates that the function if shifted to the left h units.

$f(x)=f(x)-k$ indicates that the function if shifted down k units.

$f(x)=f(x)+k$ indicates that the function if shifted up k units.

Then:

If h is positive, the graph will shift to the right.

If k is negative, the graph will shift down.

As you can see in the graph, the function is shifted 4 units to the right and 2 units down. Therefore g(x) has the form:

$g(x)=(x-4)^3-2$

Where:

$h=4\\k=-2$
