PLEASE HELP GIVING BRAINLIEST I NEED TO PASS THIS CLASS!!!The graph of an exponential function of the form y = f(x) = a^x passes through the points_____       and ____ . The graph lies ____ the x-axis.

Answers

Answer 1
Answer: y = f(x) = a^x is an expo function with constant base a and exponent x.  First, let's assume that a is positive and lying either in (0,1) or (1, infinity).

If a satisfies  0<a<1, then the expo fn is decreasing with x.  Its y-intercept is (0,1) because a^0 = 1 for all a that satisfy (0,1).  Same is true for (a>1). 

In both cases the horiz. asymptote is the line y=0.

y = f(x) = a^x has only one intercept, the y-intercept, (0,1).  

However, z = f(x) = a^x + C could have an x-intercept for certain C.

-7.12 = -4.8+× what is the answer?

Answers

You need to get the variable by itself, right? To do that, you need to get rid of the -4.8, and to do that, you need to add 4.8 to each side. -4.8 + 4.8 is 0. -7.12 + 4.8 is -2.32 (because you're adding them; however, since the number with the negative is larger, you keep the sign).

Your answer is -2.32

Don't forget to choose which answer is Brainliest!

Simplify both sides of the equation

-7.12 = x-4.8

Flip the equation

x - 4.8 = -7.12

Add 4.8 to both sides

x-4.8+4.8 = -7.12 + 4.8

x = -2.32

Step-by-step explanation:

98 = 188t - 16t^2

-16t^2 + 188t = 98

-16t^2 + 188t - 98 = 0

8t^2 - 94t + 49 = 0

Use the quadratic formula with a = 8 , b = -94 , c = 49 to get the solutions

t = [(47 - root 1817) / 8]≈ 0.55

and

t = [(47 + root 1817) / 8] ≈ 11.20
