The answer is:
The function intercepts de x-axis at "x" equal to 1.631.
Why?To find the x-intercept of the function, we need to make f(x) or "y" equal to 0, and then, isolate "x".
So, isolating we have:
Hence, we have that the function intercepts de x-axis at "x" equal to 1.631.
Have a nice day!
Note: I have attached a picture for better understanding.
Ответ:
y – 1/3 = 3/4 (x – 4)
Step-by-step explanation:
The equation of a line is given by
Where
m is the slope, and
is the coordinates of the point given
It is giventhat the slope is 3/4, so m = 3/4. Also, the point is (4, 1/3) so this is
Plugging it into the formula, we get:
Hence, 2nd option is the right answer.
