What is the inverse of f(x)=3x-1

Mathematics
1 answer:
tatiyna3 years ago
3 0

Answer:

$ \frac{(y + 1)}{3} $

Step-by-step explanation:

Call $ f(x) = y = 3x - 1 $

Now, $ y + 1 = 3x $

$ \implies \frac{y + 1}{3} = x $

This is the inverse of the given function.

You can cross - verify it by substituting a point, say, $ (1,3) $

We see that the point satisfies both the equations.

When Famke charges her phone, it gains 222 percentage points each minute. When Famke uses her phone, it loses 555 percentage poi
Charra [1.4K]
To answer this you can use a guess and check strategy.

Start with 5 minutes using it (25% lost) and 10 minutes charging (20% gained).

Try 7 minutes using it (35% lost) and 14 minutes charging (28%).

Next, 9 minutes (45%) and 18 minutes(36%).

10 minutes (50%) and 20 minutes (40%). This is the difference.

She used it for 10 minutes and charged it for 20 minutes.

We want to find the zeros of this polynomial:
fredd [130]

Answer:

x = -3 and x = -3/2

Step-by-step explanation:

After writing down the polynomial, split it; put a line between 3x^2 and -18x. Look and 2x^3 + 3x^2 and -18x - 27 separately and factor them both:

p(x) = 2x^3 + 3x^2 <u>- 18x -27</u>

p(x) = x^2(2x+3) <u>-9(2x+3)</u>

Now notice how x^2 and -9 have the same factor (2x+3). That means x^2 and -9 can go together:

p(x) = (x^2 - 9)(2x+3)

Factor it once more because there's a difference of squares:

p(x) = (x+3)(x-3)(2x+3)

Now just plug in whatever makes the each bracket equal 0:

x = -3, x = 3, and x = -3/2

Those are your zeros.
