Answer:

a) 6 b) 1 c) 9 d) -9

Step-by-step explanation:

a) go to -8 on the x-axis. Then go to the graph and see what the y value is.

I get 6. Therefore, f(-8) = 6

Do the same thing for b)

b) f(0) = 1

c) Go to -5 on the y-axis. Then go to the graph and see what the x value is

I get 9. Therefore f(9) = -5

Do the same thing for d)

d) f(-9) = 7

And that's how you use the graph to answer those questions. OK?

Solve for x: 2x^5/3-22=464 a) x = 28 b) x = 27 c) x = ±27 d) x = ±28

Effectus [21]

Answer:

Step-by-step explanation:

Given the expression ${2x^{\frac{5}{3} }-22 = 464$ , we are to find the value of x in the expression. This is as shown below;

${2x^{\frac{5}{3} }-22 = 464$

add 22 to both sides

${2x^{\frac{5}{3} }-22 = 464+22\\\\$

${2x^{5/3} =486$

divide both sides by 2

$\frac{2x^{5/3}}{2} =\frac{486}{2}\\ x^{5/3} = 243$

raise both sides to the power of 3/5

$(x^{5/3})^{3/5} = (243)^{3/5}\\x = (\sqrt[5]{243}) ^3\\x = 3^3\\x = 27$

Hence the value of x is 27
