What is the value of f(3) when f(x) = 4x + 1
valentina_108 [34]

Here is the equation:

f(x)=4x+1

You need to find f(3). To do that, substitute all the x's with 3:

f(x)=4x+1 \rightarrow f(3)=4\times3 + 1

The first thing you need to do is multiply 4 by 3. Multiply:

4 \times 3 = 12

Here is your new equation:

f(3)=12+1

To get your answer, you need to add 12 and 1. Add:

12+1 = 13

That means:

\bf f(3)=13

Write the point-slope form of the equation of the line through the given point woth the given slope
Andrej [43]

Answer:

3.) \displaystyle y - 4 = 4[x - 1]

2.) \displaystyle y + 5 = 2[x + 2]

1.) \displaystyle y + 3 = 1\frac{1}{5}[x + 5]

Step-by-step explanation:

In the Point-Slope Formula, \displaystyle y - y_1 = m[x - x_1],all the negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL inserting the coordinates into the formula with their CORRECT SIGNS.

* \displaystyle 1\frac{1}{5} = \frac{6}{5}
