(a) Complete the table of values for y- 2x + 5 - 0 1 2 1 5 Y

maxonik [38]

Answer:

Step-by-step explanation:

I think you meant y = -2x + 5.

x y = -2x + 5

0 5

1 -2(1) + 5 = 3

2 -2(2) + 5 = 1

Note that every time you increase x by 1, y decreases by 2.

What is the equation in point slope form of a line that passes through the point (−8, 2) and has a slope of 12 ? Drag a number,

NemiM [27]

Point-slope form:

y − b = m(x − a), where m is the slope and (a, b) is a point on the graph.

Here that would look like:

y - 2 = 12(x - (-8))
y - 2 = 12(x + 8)

The answer:
y - 2 = 12(x + 8)

Hope this helps.

Which of the following represents the graph of f(x) = one−half to the power of x?

puteri [66]

f(x) = $\frac{1}{2}^x$

In this exponential function , the base is $\frac{1}{2}$

if base is less than 1 then it a decreasing function

We can verify it using a table

We plug in some x and values and find out f(x) to get point for the graph

x -----> f(x)

-1 -----> 2

0 ------> 1

1 -------> 0.5

The table is same as the points in first graph.

So first graph represents the graph of f(x) = $\frac{1}{2}^x$
