x-intercept = 1/2

y- intercept = 4

Step-by-step explanation:

For finding the intercepts of a function we put x and y equal to zero respectively

Given function is:

[tex]f(x) = -8x+4[/tex]

Replacing f(x) with y

[tex]y = -8x+4[/tex]

putting y = 0

[tex]0 = -8x+4\\8x = 4[/tex]

Dividing both sides by 8

[tex]\frac{8x}{8} = \frac{4}{8}\\x = \frac{1}{2}[/tex]

Putting x = 0

[tex]y = -8(0)+4\\y = 0+4\\y = 4[/tex]

Hence,

x-intercept = 1/2

y- intercept = 4
