5x^2+7x-k(x)=0

5 x^{2} + 7 x - k (x) = 0

(h, k) = (- \frac{7}{10}, - \frac{49}{20}), p = \frac{1}{20}

Solution steps

5 x^{2} + 7 x - y = 0

Rewrite

5 x^{2} + 7 x - y = 0

in the standard form

4 \cdot \frac{1}{20} (y - (- \frac{49}{20})) = (x - (- \frac{7}{10}))^{2}

Therefore parabola properties are:

(h, k) = (- \frac{7}{10}, - \frac{49}{20}), p = \frac{1}{20}
