F(x) = -7-3x + 6x^3+x^2

(0,-7)

Steps: To find y-intercept, substitute x=0

f(0)= -7-3×0+g×0^3 +0^2

Multiply & Evaluate powers

f(0)=-7-0+6×0+0

Remove zeros. Multiply.

f(0) -7+6×0 → f(0) -7+0

Remove the zero

f(0)=-7

Hope this helps ʕ•ᴥ•ʔ

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
