Answer:

D. f⁻¹(x)=(3(x-5))/5

Step-by-step explanation:

To find the inverse of a function, change f(x) to y. Then, swap your x's and y's, and rearrange:

f(x) = 5x/3 +5

y = 5x/3 + 5

x = 5y/3 + 5

5y/3 = x - 5

5y = 3x - 15

y = (3x-15)/5

y=(3(x-5))/5

f⁻¹(x)=(3(x-5))/5

Suppose f(x)= x^2. What is the graph of g(x)= f(4x)?

melamori03 [73]

Answer:

Option A is the correct one.

Step-by-step explanation:

If f(x) = x² then g(x) = f(4x) = (4x)² = 16x² ........ (1)

Now, for any real value of x, the g(x) is positive.

Therefore, option B and option C is not correct.

Now, from the graph given in option A, it is clear that for y = 5, x value is near ± $\frac{1}{2}$ .

So, putting x = $\frac{1}{2}$ in the equation (1), we get g(x) = 16(0.5)² = 4 which is close to 5.

Therefore, option A is the correct one. (Answer)
