F(x)= 3/2 x+b
in the function above, b is a constant. if f(6)=7, what is the value of f(-2)?

F(x)=3/2 x+b
1)we have to calculate b
f(6)=7   ⇒  3/2 (6)+b=7
9+b=7
b=7-9
b=-2

Then: f(x)=3/2  x - 2

2) Now, we calculate f(-2):
f(-2)=3/2 (-2) - 2=-3-2=-5

 f(-2)=-5

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
