Question

ONE QUESTION; MEDAL AND FAN.
Solve for the y–intercept for your function, f(x)
f(x)= x^3 + 3x^2 +40x-84

Answer 1

Easy. To find a y- intercept, set x = 0
f(0) = 0^3 + 3*0^2 + 40*0 - 84 = -84
The y-intercept is -84

Answer 2

y intercept is the number with no letters by it. -48 is the only one with no x

Answer 3

\[x^3\] has an x
\[3x^2 \] has an x and a ^2
\[40x\] has an x too

-48 id the ony one with no letter or ^2
