What statement correctly describes the key features of the graph of f(x) = 4(one half)x + 1 − 3? a. y-intercept of (0, −1), starts up on the left, gets closer to y = −3 on the right b. y-intercept of (0, −1), starts down on the left, gets closer to y = −3 on the right c. y-intercept of (0, 1), starts up on the left, gets closer to y = −3 on the right d. y-intercept of (0, 1), starts down on the left, gets closer to y = −3 on the right

The correct option is B.

Explanation:

The given function is,

Put x=0 to find the y-intercept.

At x=0 the value of f(x) is -1, therefore the y- intercept is (0,-1).

Since it is an exponential function in the form of,

Where, 0<a<1, so,

Therefore the starts up on the left, gets closer to y = −3 on the right. So the option B is correct.

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

answer: -1
