Answer: C
Step-by-step explanation: Cross multiply.
36/90 = x/100
3600/90 = 40
Solve for c by simplifying both sides of the equation then isolating the variable.
c = -32.77777777
Wea re given with <span>f(x)=ax^3+bx^2+cx+d
</span>
taking the first derivative
<span>f′(x) = 3ax2 + 2bx + c
substituting the conditions to the original equation
</span><span>f(−3)=4=> -27a + 9b−3c+d
</span><span>f(2)=0=>8a+4b+2c+d
</span>f′(−3)=0=>27a−6b+<span>c
</span><span>f′(2)=0=>12a+4b+c
solving through the 4x4 solver
a = 8/125
b=12/125
c=-1.152
d=1.408
The equation is equal to </span>8/125 x^3 + <span>12/125 x^2 -1.152 x + 1.408.</span><span>
