<u><em>When x = -2</em></u>, f(x) = -7(-2) + 3 = 14 + 3

<u><em>x = 17</em></u>

<u><em>When x = 5</em></u>, f(x) = -7(5) + 3 = -35 + 3

<u><em>x = -32</em></u>

All you have to do to solve the function is substitute the value of x into the equation.

Answer:

when x=-2, f(x)=17


when x=0, f(x)=3


when x=5, f(x)=-32


Step-by-step explanation:

f(x)=-7x+3 when x=-2, 0 and 5

when x=-2,

f(x)=f(-2)

=-7*(-2)+3

=14+3

=17


when x=0,

f(x)=f(0)

=-7*(0)+3

=0+3

=3


when x=5,

f(x)=f(5)

=-7*(5)+3

=-35+3

=-32
