Answer:
40x²+2x-21
Step-by-step explanation:
4x × 10x - 4x × 7 + 3×10x - 3 × 7
40x² - 28x + 30x - 21
40x²+2x-21
4x³ + 10x² - 6x
Factor.
= 2x ( 2x - 1 ) ( x + 3 )
Answer:
The y-intercept is (0,210)
Step-by-step explanation:
We have the function,
So, we know that,
<em>'y-intercept is the point on the graph where the function crosses y-axis'.</em>
i.e. y-intercept is obtained when x=0.
Thus, substituting x=0 in the given function, we get,
i.e.
i.e.
i.e.
i.e. f(0) = 210
Also, we can see from the given graph that the function crosses y-axis at (0,210).
Hence, the y-intercept is (0,210).
