intercepts of f(x)=5cos(pi/4 x)

intercepts

f (x) = 5 cos (\frac{π}{4} x)

X Intercepts : (2 + 8 n, 0), (6 + 8 n, 0), Y Intercepts : (0, 5)

Solution steps

x -

axis interception points of

5 cos (\frac{π}{4} x) : (2 + 8 n, 0), (6 + 8 n, 0)

y -

axis interception point of

5 cos (\frac{π}{4} x) : (0, 5)

X Intercepts : (2 + 8 n, 0), (6 + 8 n, 0), Y Intercepts : (0, 5)

f (x) = - 4 x + 2

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

y = - 4 x - 1

\frac{1 - x ^{2}}{2 - x}
