Step-by-step explanation:
By the fundamental theorem of calculus,
<em>f(x)</em> = <em>f</em> (0) + ∫₀ˣ <em>f '(t)</em> d<em>t</em>
We're given that the plot of <em>f(x)</em> passes through the point (0, -7), so <em>f</em> (0) = -7, and
<em>f(x)</em> = -7 + ∫₀ˣ (9<em>t</em> ² + 4<em>t</em> - 4) d<em>t</em>
<em>f(x)</em> = -7 + (3<em>t</em> ³ + 2<em>t</em> ² - 4<em>t</em> )|₀ˣ
<em>f(x)</em> = -7 + (3<em>x</em> ³ + 2<em>x</em> ² - 4<em>x</em>)
<em>f(x)</em> = 3<em>x</em> ³ + 2<em>x</em> ² - 4<em>x</em> - 7
To find this answer, we subtract each of the like terms in the equation. 3x and 3x are like terms, -4y and 2y are like terms, and 7 and -5 are like terms. Now we subtract. 3x - 3x is 0, -4y - 2y is -6y, and 7 - (-5) is 12. That means that the result is -6y = 12, or B.
