C. [Sorry if it's wrong.]
Step-by-step explanation:
I haven't taken this test but when looking at the photo, it looked like they intercepted at (0, 2).
So with this, you'll be using a proportion to solve it. And here's what your equation will look like:
Firstly, you'll need to cross-multiply. Your equation will look like this:
For this, all you need to do is square root, and your answer is , however this answer can be simplified further.
In short, your answer is
The answer should be x = 3
For every f(x) change the x with the given value.
a.
x³-5x²+6x-4 ..........change the x with 2
(2)³-5(2)²+6(2)-4
8-20+12-4
-4
b.
4x³+3x²+x+2 .... .same here change x to 1
4(1)³+3(1)²+(1)+2
4+3+1+2
10
c.
2x^4-x³+3x²-1 ...........change x as -1
2-(-1)³+3(-1)²-1
2+1+3-1
5
d.
2x³-6x-5 ................change x with -3
2(-3)³-6(-3)-5
2(-27)+18-5
-41
