f(x)=-x^2+9x+12

Solution

f (x) = - x^{2} + 9 x + 12

Solution

Domain : - \infty < x < \infty

Range : f (x) \leq \frac{129}{4}

X Intercepts : (- \frac{- 9 + 129}{2}, 0), (\frac{9 + 129}{2}, 0), Y Intercepts : (0, 12)

Vertex : Maximum (\frac{9}{2}, \frac{129}{4})

Inverse : - \frac{- 9 + - 4 x + 129}{2}, - \frac{- 9 - - 4 x + 129}{2}

f(x)=5x^2-2x-10

f (x) = 5 x^{2} - 2 x - 10

f(x)=x-3+8x^2-4x+15

f (x) = x - 3 + 8 x^{2} - 4 x + 15

y=((50t^2+300t+1500))/((t^2+30))

y = \frac{( 50 t ^{2} + 300 t + 1500 )}{( t ^{2} + 30 )}

f(y)=6y^2+7y-48

f (y) = 6 y^{2} + 7 y - 48

f(x)= 1/(6*ln((x^2-2sqrt(2x^2-2))^4))

f (x) = \frac{1}{6 \cdot ln ( ( x ^{2} - 2 2 x ^{2} - 2 ) ^{4} )}
