2x+x+2+40=180

3x+42=180

3x=138

x=46

(then plug in X)

2*46= 92

Your answer is 92

Match each transformation of function fwith a feature of the transformed function.
Grace [21]

The functions and their properties are

  • The function f(x) has its vertical asymptote at x = 0
  • The x-intercept of the function h(x) is (0.5,0)

<h3>How to match the functions and their properties?</h3>

The equations of the functions are given as:

f(x) = ln(x)

g(x) = -1/2f(x - 2)

h(x) = f(x - 1/2)

From the given graph, we can see that the function f(x) has its vertical asymptote at x = 0

h(x) = f(x - 1/2) implies that the function f(x) is shifted 1/2 units right to form h(x)

This means that the x-intercept of the function h(x) is 1/2 units to the right of the x-intercept of the function f(x)

Hence, the x-intercept of the function h(x) is (0.5,0)

Help Pre-Calc
Anna11 [10]

Answer:

Average rate of change = 2

Step-by-step explanation:

We need to find the average rate of change of f(x) over the interval [-4,-1], so first we need to find the end points at x=-4 and x=-1.

From graph we see that y=-3 when x=-4, So the point is (-4,-3)

From graph we see that y=3 when x=-1, So the point is (-1,3)

Now we can plug these points into average rate of change formula:

Average\ rate=\frac{f\left(b\right)-f\left(a\right)}{b-a}

where (a,f(a)) and (b,f(b)) are the given points.

Average\ rate=\frac{-3-3}{-4-\left(-1\right)}

Average\ rate=\frac{-3-3}{-4+1}

Average\ rate=\frac{-6}{-3}

Average\ rate=2

Hence final answer is 2.
