Consider the linear function f(x)=4x-5 Find the values of x for which f(x)=3,f(x)=5,f(x)=-3
Evgesh-ka [11]

Answer:

f(2) = 3

f(5/2) = 5

f(½) = -3

Step-by-step explanation:

Given the linear function f(x) = 4x - 5:

<h3>f(x) = 3</h3>

3 = 4x - 5

3 + 5 = 4x - 5 + 5

8 = 4x

8/4 = 4x/4

2 = x

Therefore, when f(x) = 3, x = 2.

<h3>f(x) = 5</h3>

5 = 4x - 5

5 + 5 = 4x - 5 + 5

10 = 4x

10/4 = 4x/4

5/2 = x

Therefore, when f(x) = 5, x = 5/2.

<h3>f(x) = -3</h3>

-3 = 4x - 5

-3 + 5 = 4x - 5 + 5

2 = 4x

2/4 = 4x/4

½ = x

Therefore, when f(x) = -3, x = ½.

Which function is graphed on the right?
Norma-Jean [14]

Answer: y=2^{x-2}+3

Step-by-step explanation:

To find the equation from a graphed function, you can substitute points into each equation to find the original:

A point on the graph is (2, 4). Substituting this into each equation, we get:

4=2^{2+3} -2, which claims that 4 is equal to 30, which is incorrect.

4=2^{2-3} +2, which claims that 4 is equal to 3/2, which is incorrect.

4=2^{2-2}+3, which claims that 4 is equal to 4, which is correct.

We can test the third function further by taking another point on the graph, (3, 5), and substituting it into the function:

5=2^{3-2} +3, which claims that 5 is equal to 5, which is correct.

Dimas [21]

Answer:

C= 38 in Approx

A=113 in^2 Aprprox

Step-by-step explanation:

Given data

radius= 6 ft

Circumference, C=2πr

substitute

C=2*3.142*6

C=37.704 in

Area A= πr^2

substitute

A=3.142*6^2

A=3.142*36

A=113.112 in^2
