Y = 3x + 4<br> What is the y-intercept?<br> What is the slope?
AnnyKZ [126]

Answer:

  • Slope = 3
  • Y-intercept = 4

Step-by-step explanation:

Our equation:

  • y = mx + b

Given equation:

  • y = 3x + 4

Now, let's compare both the equations.

=> y = mx + b = y = 3x + 4

We can clearly see that 'm = 3 and b = 4'

Therefore:

  • m = 3
  • b = 4

Hoped this helped.

Find f^-1 (12) if x f(x)=3x-7
saveliy_v [14]

Answer:

The value of f^{-1}(12) is \frac{7}{-9} .

Step-by-step explanation:

The given equation is <em>x f(x) = 3x-7 .</em>

f(x)=3-\frac{7}{x}

The inverse of the function is found by adjusting the equation such that, expressing x in terms of f(x).

\frac{7}{x} = 3 - f(x)

x = \frac{7}{3-f(x)}

now, <em>x = f^{-1}(x) and f(x) be x.</em>

Thus, f^{-1}(x) = \frac{7}{3-x}

Now, inserting value of x as 12,

<em>f^{-1}(12) = \frac{7}{3-(12)}</em>

<em>f^{-1}(12) = \frac{7}{-9}</em>
