Hat function is represented by a line with slope −2 that passes through the point (0, 4)? A. f(x) = 2x + 4
B. f(x) = 2x − 4
C. f(x) = −2x + 4
D. f(x) = −2x − 4

C

Step-by-step explanation:

You can use the formula y=mx+b

f(x) is the same as y

m=slope

b=y intercept

We know that the slope is -2 so which answer has -2 as b? (Which one has a -2 before the x?)

Y Intercept is where the line crosses though the y axis. The point of the y intercept will ALWAYS have 0 as x. So (0,4) is the y intercept. You could also say 4 is the y intercept. Which one has 4 as b? (Which one says +4 after -2x)

The only answer that matches is C.

I hope thay made sense.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
