intercepts of f(x)=x^2-4x-21

intercepts

f (x) = x^{2} - 4 x - 21

X Intercepts : (7, 0), (- 3, 0), Y Intercepts : (0, - 21)

Solution steps

x -

axis interception points of

x^{2} - 4 x - 21 : (7, 0), (- 3, 0)

y -

axis interception point of

x^{2} - 4 x - 21 : (0, - 21)

X Intercepts : (7, 0), (- 3, 0), Y Intercepts : (0, - 21)

f (x) = (6 - 2 x)^{\frac{9}{2}}

- \frac{5}{4}

7 x + 4 y = 28

f (x) = 9^{x}

e^{7 x}
