Suppose k(w)=2^w.
(a) Find a formula for y=k(w)+7
Well, if we're adding 7 to k(w), that means we're adding 7 to 2^w in this case. So, the formula for y would be y = 2^w + 7. But remember, adding 7 makes everything better... well, except maybe your cholesterol levels.
To find a formula for y given k(w)=2^w and y=k(w)+7, you simply substitute the expression for k(w) into the equation for y and simplify.
Step 1: Substitute k(w)=2^w into y=k(w)+7.
y = 2^w + 7
So, the formula for y is y = 2^w + 7.
