<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

2(5-n)=-2+(-1*n)
2(5-n)=-n-2
distribute
10-2n=-n-2
add 2n to both sides
10=n-2
add 2 to both sides
12=n
